Dealing with special hard drive partitions
The OP [Urge] has presented issues which may relate to special partitions
which may be found upon notebooks, laptops, or other computers [such as Dell, HP, Compaq, Gateway, etc.]. This aspect of the query revolves around potentials when reinstalling OSs, reformatting hard drives, or otherwise; when potentially confronted with diagnostic and other [hidden] partitions. As the matter has not been responded to for two days, I thought it best to bring a separate discussion to bear. SHORT background [via Urge]: I setup another computer with Win98se ( an old HP Brio that I rescued from the dump) and Drive Image works on it just fine. There is nothing in Config.sys or Autoexec.bat pertaining to cd-rom drives. My original question was about a Compaq 5100 dating from 1995 that has a peculiar bios setup that requires software on your harddrive to access the bios. When I got this computer it was password protected and I just wiped everything off and started over ( I didn't know about the bios issue at the time). It does not appear to me that I can get the necessary software from the Compaq (HP) site. There are no key combinations you can push to enter the bios without this software. My question is, could there be any settings in the bios that would prevent the cdrom drive from being recognized by Drive Image. ---------- Urge found information concerning the potential for a needed partition and/or its containments [indicated by a potential 12H], and requested information concerning such. Original post is listed as "can't access cd drive in dos". Please respond under this heading. 12h 1. Compaq/HP Diagnostics/hibernation FAT partition 2. Intel ROM-DOS Service Partition 3.

Urge's known partition per fdisk is 1038 MB listed as drive C. Total hard drive space was presented as 2 gig, on a Compaq 5100 dating from 1995. Compaq has a number of computers listed under 5100 numbering, but based upon age and the notebook/laptop it must be an LTE. It was also stated that apparently this "other" potential partition held the BIOS/CMOS access coding. There appears to be, or may be, a BIOS update available according to Google on driversguide but downloading those appeared to bring the wrong files (several checked locally - apparently for different models) for the laptop/notebook: However HP/Compaq has its own site with an array of drivers and necessary software for the LTE 5100 [which apparently came installed with Win95]: http://h20000.www2.hp.com/bizsupport...35&swEnvOID=19 System ROMPaq 7.32 A 22 Jul 1998 1.1 56K: 2m 512K: 1m .7.20 A 20 Feb 1998 sp7804.exe - which creates the diskette for the ROM update Under: Software - System Management Computer Setup and Diagnostics for Portables 1.12 B 6 Nov 1996 2.3 56K: 5m 512K: 1m sp2054.exe - which creates the setup diskette This MIGHT be the file necessary to get into the BIOS/CMOS for computer setup. Urge, please post back whether these helped with your issues. ------- Perhaps we can now discuss the issues of other types of partitions which might be found and/or necessary for various OSs and/or manufacturers. SUCH AS: debug routines which might be useful for identifying partition types or working with hard drives; tools useful when working with partitions and MBR; other partition types and their effects. Partition types [DOS, network, manufacturer specific, and Microsoft] which might be of interest {leaving out Linux?BEOS variants and others unless also listed per noted}. Boot and disk managers, and manufacturers hidden/diagnostic partitions are of special interest. Hopefully we have some experts familiar with some of these, and their effects on hard drives.

Windows NT Disk Administrator hidden partition Windows NT Disk Administrator marks hidden partitions (i.e. present but not to be accessed) as type FEh. A primary partition of this type is also used by IBM to hold an image of the "Reference Diskettes" on many of their machines, particularly newer PS/2 systems (at a rough guess, anything built after about 1994). This clash can cause major confusion and grief if running NT on IBM kit. When this Reference Partition is activated, it changes its type into 1 (FAT12) and hides all other partitions by adding 10h to the type. 2. SpeedStor over 1024 cyl. 3. LANstep 4.

It was also stated that apparently this "other" potential partition held the BIOS/CMOS access coding. The computer in question is in fact a Compaq Deskpro 5100 Desktop PC series. It is not a laptop or portable. The hard drive has a total of 1 gig. I successfully applied the following bios update but it did nothing as far as letting me into the bios. I didn't expect that it would cause I still need to set up the diagnostics partition. I want to create a 2 MB partition at the beginning of my hard drive(with Partition Magic) and try the diagnostic software again. Does this seem reasonable? Will this partition stop my OS from loading? If this partition is created will the Compaq software maybe find an appropriate entry in the Master Boot Record? from my earlier post... "To install the Compaq utilities, you must free at least 2 megabytes of drive space at the beginning of the hard drive. You must have an available entry in the master boot record for the partition information. Caution: if a partition exists of type 12H, do not remove it from the master boot record. If this partition is at the beginning of the hard drive, it will be increased in size to make room for the Compaq utilities."

Dealing with special hard drive partitions
"Urge" wrote in message ... | | "MEB" meb@not wrote in message | ... | | | | "MEB" meb@not wrote in message | ... | | The OP [Urge] has presented issues which may relate to special | partitions | | which may be found upon notebooks, laptops, or other computers [such as | | Dell, HP, Compaq, Gateway, etc.]. This aspect of the query revolves | around | | potentials when reinstalling OSs, reformatting hard drives, or | otherwise; | | when potentially confronted with diagnostic and other [hidden] | partitions. | | | | As the matter has not been responded to for two days, I thought it best | to | | bring a separate discussion to bear. | | | | SHORT background [via Urge]: | | I setup another computer with Win98se ( an old HP Brio that I rescued | from | | the dump) and Drive Image works on it just fine. There is nothing in | | Config.sys or Autoexec.bat pertaining to cd-rom drives. My original | | question was about a Compaq 5100 dating from 1995 that has a peculiar | bios | | setup that requires software on your harddrive to access the bios. When | I | | got this computer it was password protected and I just wiped everything | off | | and started over ( I didn't know about the bios issue at the time). It | does | | not appear to me that I can get the necessary software from the Compaq | (HP) | | site. There are no key combinations you can push to enter the bios | without | | this software. My question is, could there be any settings in the bios | that | | would prevent the cdrom drive from being recognized by Drive Image. | | ---------- | | | | Urge found information concerning the potential for a needed partition | | and/or its containments [indicated by a potential 12H], and requested | | information concerning such. Original post is listed as "can't access cd | | drive in dos". Please respond under this heading. | | | | 12h | | 1. Compaq/HP Diagnostics/hibernation FAT partition | | 2.

Total hard | drive space was presented as 2 gig, on a Compaq 5100 dating from 1995. | Compaq has a number of computers listed under 5100 numbering, but based | upon | age and the notebook/laptop it must be an LTE. It was also stated that | apparently this "other" potential partition held the BIOS/CMOS access | coding. | | The computer in question is in fact a Compaq Deskpro 5100 Desktop PC series. My mistake, must have read that from the other referenced computer.. | It is not a laptop or portable. The hard drive has a total of 1 gig. I | successfully applied | the following bios update but it did nothing as far as letting me into the | bios. I didn't expect | that it would cause I still need to set up the diagnostics partition. I | want to create a 2 MB partition | at the beginning of my hard drive(with Partition Magic) and try the | diagnostic software again. | Does this seem reasonable? Will this partition stop my OS from loading?

Nothing should be installed on the hard disk when using these disks. Make sure you create extra copies of the floppy disks created and write protect them. From the file: Computer SETUP/V and PC Diagnostics F10 Setup/V, with Personal Computer Diagnostics, supports the Compaq Deskpro 2000 series (excluding the 2000MMX) of personal computers.

Dealing with special hard drive partitions

"MEB" meb@not wrote in message ... "MEB" meb@not wrote in message ... | The OP [Urge] has presented issues which may relate to special partitions | which may be found upon notebooks, laptops, or other computers [such as | Dell, HP, Compaq, Gateway, etc.]. This aspect of the query revolves around | potentials when reinstalling OSs, reformatting hard drives, or otherwise; | when potentially confronted with diagnostic and other [hidden] partitions. | | As the matter has not been responded to for two days, I thought it best to | bring a separate discussion to bear. | | SHORT background [via Urge]: | I setup another computer with Win98se ( an old HP Brio that I rescued from | the dump) and Drive Image works on it just fine. There is nothing in | Config.sys or Autoexec.bat pertaining to cd-rom drives. My original | question was about a Compaq 5100 dating from 1995 that has a peculiar bios | setup that requires software on your harddrive to access the bios. When I | got this computer it was password protected and I just wiped everything off | and started over ( I didn't know about the bios issue at the time). It does | not appear to me that I can get the necessary software from the Compaq (HP) | site. There are no key combinations you can push to enter the bios without | this software. My question is, could there be any settings in the bios that | would prevent the cdrom drive from being recognized by Drive Image. | ---------- | | Urge found information concerning the potential for a needed partition | and/or its containments [indicated by a potential 12H], and requested | information concerning such.

Urge's known partition per fdisk is 1038 MB listed as drive C. Total hard drive space was presented as 2 gig, on a Compaq 5100 dating from 1995. Compaq has a number of computers listed under 5100 numbering, but based upon age and the notebook/laptop it must be an LTE. It was also stated that apparently this "other" potential partition held the BIOS/CMOS access coding. The computer in question is in fact a Compaq Deskpro 5100 Desktop PC series. It is not a laptop or portable. The hard drive has a total of 1 gig. I successfully applied the following bios update but it did nothing as far as letting me into the bios. I didn't expect that it would cause I still need to set up the diagnostics partition. I want to create a 2 MB partition at the beginning of my hard drive(with Partition Magic) and try the diagnostic software again. Does this seem reasonable? Will this partition stop my OS from loading? If this partition is created will the Compaq software maybe find an appropriate entry in the Master Boot Record? from my earlier post... "To install the Compaq utilities, you must free at least 2 megabytes of drive space at the beginning of the hard drive. You must have an available entry in the master boot record for the partition information. Caution: if a partition exists of type 12H, do not remove it from the master boot record. If this partition is at the beginning of the hard drive, it will be increased in size to make room for the Compaq utilities."

Urge There appears to be, or may be, a BIOS update available according to on driversguide but downloading those appeared to bring the wrong files (several checked locally - apparently for different models) for the laptop/notebook: However HP/Compaq has its own site with an array of drivers and necessary software for the LTE 5100 [which apparently came installed with Win95]: http://h20000.www2.hp.com/bizsupport...35&swEnvOID=19 System ROMPaq 7.32 A 22 Jul 1998 1.1 56K: 2m 512K: 1m .7.20 A 20 Feb 1998 sp7804.exe - which creates the diskette for the ROM update Under: Software - System Management Computer Setup and Diagnostics for Portables 1.12 B 6 Nov 1996 2.3 56K: 5m 512K: 1m sp2054.exe - which creates the setup diskette This MIGHT be the file necessary to get into the BIOS/CMOS for computer setup. Urge, please post back whether these helped with your issues. ------- Perhaps we can now discuss the issues of other types of partitions which might be found and/or necessary for various OSs and/or manufacturers. SUCH AS: debug routines which might be useful for identifying partition types or working with hard drives; tools useful when working with partitions and MBR; other partition types and their effects. Partition types [DOS, network, manufacturer specific, and Microsoft] which might be of interest {leaving out Linux?BEOS variants and others unless also listed per noted}. Boot and disk managers, and manufacturers hidden/diagnostic partitions are of special interest. Hopefully we have some experts familiar with some of these, and their effects on hard drives.

If I use fdisk am going to hose my OS? Didn't you just reinstall the OS? So what with the worrying about whether you need to wipe the disk again for a proper installation? Here you've spent several DAYS discussing possiblities, when to reinstall the OS AFTER using the F10 setup disk on a blank hard disk would take what, 30-45 minutes. Will it be hosed, gees, it might be. Then again MAYBE you can move the OS partition back 2 1/2 megs or so [remember you don't really know the exact amount needed] from the beginning of the hard disk with Partition Magic, install the F10 and diagnostics, and MAYBE just have to do something like "sys c:" afterwards, maybe not even that; can't really tell you for sure. Depends upon your skill, your hard disk, what the MBR already contains, BIOS/CMOS settings, whether the installer will accept that, or any number of other potential issues. Were the original partition still there, then likely the answer would be NO, go ahead... were you able to review the BIOS/CMOS settings then again likely NO go ahead, but we don't have ANYTHING concerning the present configuration of the computer to work from. I see you've looked at the manual, what did it suggest? And I present this because, while searching for information, I noted potential issues with disks over * megs [likely corrected with that BIOS update], models of Hard drives, etc..

I would prefer you use something like TESTDISK or some other | tool to look at/diagnose the hard drive first though. | | If this is a Maxtor disk, note there is a firmware update for that as | well. | | | | | from my earlier post... | | | | "To install the Compaq utilities, you must free at least 2 megabytes of | | drive space at the beginning of the hard drive. | | You must have an available entry in the master boot record for the | partition | | information. | | Caution: if a partition exists of type 12H, do not remove it from the | master | | boot record.

Dealing with special hard drive partitions
I read thru the Compaq troubleshooting guide and looked but couldn't find
either a CMOS button or the appropriate jumper. There were only 2 jumpers in use on the MB, 1 for int/ext bat and 1 at E-6 (the manual said to look for E-49) which I had no clue about (it was next to the memory chips if that means anything). Should I try removing the jumper at E-6? Urge "Brian A." gonefish'n@afarawaylake wrote in message ... Two types of CMOS passwords can be set for that machine. You can read about them and how to reset the CMOS he http://h20000.www2.hp.com/bc/docs/su...122838-002.pdf Scroll down to the section "Password Security and Clearing and Resetting CMOS." -- Brian A. Sesko { MS MVP_Shell/User } Conflicts start where information lacks. http://basconotw.mvps.org/ Suggested posting do's/don'ts: http://www.dts-l.org/goodpost.htm How to ask a question: http://support.microsoft.com/kb/555375 "Urge" wrote in message ... "MEB" meb@not wrote in message ... "MEB" meb@not wrote in message ... | The OP [Urge] has presented issues which may relate to special partitions | which may be found upon notebooks, laptops, or other computers [such as | Dell, HP, Compaq, Gateway, etc.]. This aspect of the query revolves around | potentials when reinstalling OSs, reformatting hard drives, or otherwise; | when potentially confronted with diagnostic and other [hidden] partitions. | | As the matter has not been responded to for two days, I thought it best to | bring a separate discussion to bear. | | SHORT background [via Urge]: | I setup another computer with Win98se ( an old HP Brio that I rescued from | the dump) and Drive Image works on it just fine. There is nothing in | Config.sys or Autoexec.bat pertaining to cd-rom drives. My original | question was about a Compaq 5100 dating from 1995 that has a peculiar bios | setup that requires software on your harddrive to access the bios. When I | got this computer it was password protected and I just wiped everything off | and started over ( I didn't know about the bios issue at the time). It does | not appear to me that I can get the necessary software from the Compaq (HP) | site. There are no key combinations you can push to enter the bios without | this software. My question is, could there be any settings in the bios that | would prevent the cdrom drive from being recognized by Drive Image. | ---------- | | Urge found information concerning the potential for a needed partition | and/or its containments [indicated by a potential 12H], and requested | information concerning such. Original post is listed as "can't access cd | drive in dos". Please respond under this heading. | | 12h | 1. Compaq/HP Diagnostics/hibernation FAT partition | 2. Intel ROM-DOS Service Partition | 3. EISA partition | | Check first by using "fdisk /status" at a dos prompt, and posting what is | shown back to this group. | | MEB | | Alright, here it is. please don't make fun of my hard drive. | I'm assuming that the 100% usage is referring to the drive being 1 partition | that uses the entire drive. I have Partition Magic and could add a 2 MB | partition at the beginning? of the drive. | Urge | | DISK DRV MBYTES FREE USAGE | 1 1036 100% | C: 1038 | | | | -- | MEB | _______________ | | Okay, let's see if I can jump start this discussion. Urge's known partition per fdisk is 1038 MB listed as drive C. Total hard drive space was presented as 2 gig, on a Compaq 5100 dating from 1995. Compaq has a number of computers listed under 5100 numbering, but based upon age and the notebook/laptop it must be an LTE. It was also stated that apparently this "other" potential partition held the BIOS/CMOS access coding. The computer in question is in fact a Compaq Deskpro 5100 Desktop PC series. It is not a laptop or portable. The hard drive has a total of 1 gig. I successfully applied the following bios update but it did nothing as far as letting me into the bios. I didn't expect that it would cause I still need to set up the diagnostics partition. I want to create a 2 MB partition at the beginning of my hard drive(with Partition Magic) and try the diagnostic software again. Does this seem reasonable? Will this partition stop my OS from loading? If this partition is created will the Compaq software maybe find an appropriate entry in the Master Boot Record? from my earlier post... "To install the Compaq utilities, you must free at least 2 megabytes of drive space at the beginning of the hard drive. You must have an available entry in the master boot record for the partition information. Caution: if a partition exists of type 12H, do not remove it from the master boot record. If this partition is at the beginning of the hard drive, it will be increased in size to make room for the Compaq utilities."

Urge, please post back whether these helped with your issues. ------- Perhaps we can now discuss the issues of other types of partitions which might be found and/or necessary for various OSs and/or manufacturers.

Partition types [DOS, network, manufacturer specific, and Microsoft] which might be of interest {leaving out Linux?BEOS variants and others unless also listed per noted}. Boot and disk managers, and manufacturers hidden/diagnostic partitions are of special interest. Hopefully we have some experts familiar with some of these, and their effects on hard drives.

If I use fdisk am going to hose my OS? Didn't you just reinstall the OS? So what with the worrying about whether you need to wipe the disk again for a proper installation? Here you've spent several DAYS discussing possiblities, when to reinstall the OS AFTER using the F10 setup disk on a blank hard disk would take what, 30-45 minutes. If it was only 30-45 minutes I would have done that already. After install I updated DirectX, IE6,all windows updates, all OE updates, Java, MDAC, and WMP. The whole purpose of this exercise was to not have to do this again. If I could burn an image file of the drive I could reinstall in 20 minutes or so if necessary. I also have 2 additional computers (all 3 computers obtained for free from a business that didn't want them anymore) that are virtually identical that I could use this on also. My wife and I have a small business and we use these at work (we need 2) so I have a spare (they are old). Earlier I suggested using Partition Magic to add a partition for the diagnostics but someone else thought that was a bad idea. I still would like to know how to access my MBR and see what it contains but I have no clue on how to go about that. Will it be hosed, gees, it might be. Then again MAYBE you can move the OS partition back 2 1/2 megs or so [remember you don't really know the exact amount needed] from the beginning of the hard disk with Partition Magic, install the F10 and diagnostics, and MAYBE just have to do something like "sys c:" afterwards, maybe not even that; can't really tell you for sure. Depends upon your skill, your hard disk, what the MBR already contains, BIOS/CMOS settings, whether the installer will accept that, or any number of other potential issues. Were the original partition still there, then likely the answer would be NO, go ahead... were you able to review the BIOS/CMOS settings then again likely NO go ahead, but we don't have ANYTHING concerning the present configuration of the computer to work from. I see you've looked at the manual, what did it suggest? And I present this because, while searching for information, I noted potential issues with disks over * megs [likely corrected with that BIOS update], models of Hard drives, etc.. So your PRIMARY consideration should be finding out what the BIOS/CMOS shows and proper settings, and what the diagnostics find, NOT the OS at present. | I will certainly | try TESTDISK but a brief Google search this morning found a number of | variations, is there one in particular I should download and try? It is not | a Maxtor disk. http://www.cgsecurity.org - home of TESTDISK , comes with extensive help in the form of Html, use it ... any questions post back. | | If that fails [since it states its an upgrade]: I hate to suggest this, | but | this may be the only tool you have: | Use a boot disk with fdisk on it and type fdisk /mbr to install a default | boot record, then attempt the F10 - Diagnostic installations after | restarting. I would prefer you use something like TESTDISK or some other | tool to look at/diagnose the hard drive first though. I downloaded TESTDISK and did some reading about it but have not tried it yet. I apologize but I'm working 7 days a week and don't always have the time or the energy to spend. I will try in the next day or 2. Urge | | If this is a Maxtor disk, note there is a firmware update for that as | well. | | | | | from my earlier post... | | | | "To install the Compaq utilities, you must free at least 2 megabytes of | | drive space at the beginning of the hard drive. | | You must have an available entry in the master boot record for the | partition | | information. | | Caution: if a partition exists of type 12H, do not remove it from the | master | | boot record.
