The Maxblast software should work, but only if the hard disk is properly
prepared for it. Simply running the program off the floppy will not
automatically give you access to the second partition. If the hard drive
was not prepared with the software this probably explains the error message.

You need to find the command in the Maxblast software that partitions the
hard drive, formats it, and installs the overlay loader into the hard drive
boot sector. This software will be accessed from floppy following a normal
DOS boot.

This process will delete everything on the hard drive, so you will need to
reinstall your operating system and restore your data files. Therefore,
make sure you have everything you need for a full restoration before
starting this procedure.

Hi,

One of my computers is a portable Compaq 386 (sold for $5,700 around
1988). It has 2 meg of ram and Dos 6.22. I replaced the 40 meg hdd
with a Quantum "Lightning" 750 meg, that was partitioned (on a newer
computer)
into two logical drives (520 meg and 230 meg). The 386 BIOS doesn't "see"
above 520 meg. Note: The MBR is the same as it was on the newer computer.
I would like to know a way to access the second 230 meg partition which
was
formatted on the newer computer. Editing the MBR, and changing the
"active" partition to the second partition, resulted in a "missing os"
error
during a reboot. If I booted from a floppy boot disk, then switched to C:
drive, I was in the "first partition drive". I put back the original
MBR.

I asked a tech support person from Maxtor, which now owns Quantum's hdd
products, where could I get an "overlay"? He told me to download
"MaxBlast"
V3.*, which I did. After creating the bootable floppy, I tried it
(bootable
floppy) on the 386 (CGA graphics system), but it couldn't complete it's
startup, perhaps due to incompatibility? The error message, "command
or filename not recognized" (no clue to what command or filename?) was
displayed and everything "locked up". Note: I found the source of that
error
message in "COMMAND.COM" (of DrDos) in that bootable floppy, created
by MaxBlast.

I searched the web for an old Quantum overlay, but I couldn't find one.
If you know a technique on how I can access the second partition, please
let
me know. Note: I don't have to access both partitions at the same time.
If
you know of a "switching" technique, that will be just fine.

Thanks in advance, Brad
