Bad Checksum (Rom) Error
I'm running a Toshiba S1800-400 LapTop, running ME. Suddenly it's starting
to play up with windows freezing producing either: - OE 017F BFF8E64B or OE 0167 BFF9A0F BSOD's Now it's refusing to boot past the safemode startup - if I check start windows normally, it just comes back to the safemode option. Booting up to safemode usually hangs the os after a minute or two and when booting, now shows "Bad Checksum (Rom)" I noticed prior to these problems, that boot up sometimes didn't occur until I tapped the Laptop and also sometimes the os would freeze when inserting a cd or dvd rom. Am I suspecting a damaged or broken CD/DVD Rom drive? Anyone else have this problem or could give me advice please?

This looks like a hardware problem to me - either the CMOS battery is dying,
or your motherboard. Try removing the main battery from the laptop, and unplugging from the mains - leave it for half an hour. Then attach to the mains again, and reboot - what exact errors do you get in trying to boot to Safe Mode??

Thanks - most helpful. I will try what you suggest and report further. I
work "nights" so it may be later in the day when I report but in the meantime I should perhaps have pointed out that in safe mode, the CD drive is not seen by Windows, even though in Device Manager it's there and is seemingly trouble free. The Main HDD, partitioned as C:\ and D:\ are running in msdoa compatibility mode, suggesting there is a fault. Running scandisk on C:\ (D is ok), results in an error message saying that "another application is preventing this utility to work on this drive, suggest closing the application and try again". As the main problem came to a head after inserting a CD rom, I just suspected the CD Rom drive. Previous to this I had to reinstall Windows ME as Windows failed to boot for some error, which I cannot now recall. After doing so and installing quite a number of programs, installing the dedicated drivers from Toshiba's site and updating windows via the update site all seemed well for a few days. I used the CD rom extensively without hitch, although from time to time after shutting the laptop down, it failed to respond to the power button, necessitating a gentle wiggle of the screen or a tap on the side or a closing and reopening of the lid. The current problem manifested whilst loading a cd as soon as the cd rom "clicked" indicating that the reading of the cd was underway, immediately the laptop froze and upon eventually getting it to boot back up, I got the "Check Sum error on Cd Rom" message but after it then booted up into windows, I got a single and brief message saying that "there is a problem with the cd rom drive please reinstall windows". Obviously I don't want to go to the trouble again of reloading windows until I have an angle on what is wrong here. I hope this further detail helps you further, to diagnose the fault(s), hopefully prior to reporting later. TAIA Paul "Noel Paton" wrote in message ...

Just to follow up - I tried what you recommended, after 6 attempts to get the thing to boot up - nothing other than what I previously reported was evidident. The date and time were ok, but scandisk refuses to operate Paul "Noel Paton" wrote in message ... This looks like a hardware problem to me - either the CMOS battery is dying, or your motherboard.

meantime I should perhaps have pointed out
that in safe mode, the CD drive is not seen by Windows, even though in Device Manager it's there and is seemingly trouble free. Paul, this is a 'red herring'! You will NOT see the CD-ROM in Windows Explorer in Safe Mode - the drivers are not loaded until it boots into Normal Mode. As for scandisk, try running it in Real Mode DOS, using your WinMe Startup (floppy) Disk. (It *may* even give you more insight to the cause of the Checksum error) And maybe there is a clue with your comment "necessitating a gentle wiggle of the screen or a tap on the side or a closing and reopening of the lid" - Mmm ... suspicious. Loose RAM chip (or worse!) perhaps? Mart "Paul" wrote in message ...
