Sometimes the Promise (and other) controllers support different LBA
translations for the drives. I ran into a situation where I had to
completely repartition and reformat a drive to make it work with one. That
may well be the case with your setup.
You may have a problem with the ISA modem. Make sure to go into your BIOS
and under PCI/PNP (or similar) be sure to reserve whatever IRQ it is using
to ISA or Legacy ISA. Make sure to do the same for all Non-PnP cards in the
Also, some BIOSes let you manually set the IRQ by PCI slot number. You may
want to give this a try.
In a setup like this I would initially use:
4 Modem (Assuming it is set as COM1 or COM3)
5 Sound Card (Some old SoundBlasters are not PNP - see above)
10 Ultra66 Adapter
11 Network Card (if installed)
The Primary onbord IDE will be IRQ 14, and the Secondary will go to 15.
Both of these are defaults that should not be messed around with.
If you want to try a repartition, first obtain a copy of Norton Ghost and
put it on a DOS boot disk, along with FDISK, FORMAT, and SYS.COM.
Make sure that the disk you want to repartition has less data in use than
you have free space on the other drive. Connect both drives to the onboard
controller and boot from a floppy that contains Ghost, and use it to create
an image of the smaller drive in a file on the larger one. Then repartition
the drive with FDISK, leaving enough free space for a later Linux install.
Then use GHOST to copy everything back.
It's kind of a pain, but sometimes you run across things like these.
