We had a working 1.2.8 slakware system running on a pentium with an older
AHA contoller.  For requirements that need not be documented here, the
controller was changed to an aha1542cp.  The Dos/win95 side boots, Lilo
is there, but when we try to boot ANY of the Linux kernels we get a panic
when mounting the root file system.  Is there any way to resurrect the
LInux partition or does it have to be reinstalled?

and thanks for your assistance.

Hi, I got tekram DC300B which is comparable with aha154x.  I have some probs.
When I use SCSI HDD with that adapter, the system goes hang over everytime.
Somebody said I should put the IRQ for buslogic when I boot up, but it
doesn't work.  This is ref. for my system;
        486DX2 66 with 8M RAM
        Slackware 3.0 with 1.2.13 kernel
        Conner CFP1060S 1G SCSI HDD with Tekram DC300B SCSI adapter
Thanks for any advice.

I had this going on after rebuilding the Kernal. I booted from an image
on a floppy entering "mount root=/dev/sda1" at the boot prompt so that
the existing Linux root file system would be used. Then login as root,
and enter "lilo". This will cause lilo to remap the linux kernal image.

I have a similar card, the first observation is that niether Pinnacle nor the manufacturer Adaptec was seemingly very interested in telling me the details of the card so that a driver could be witten.

However as I played with the card under MSDOS (no flames) it became obvious that it is really just a Bios minus 1542 or at least is indistinguishable from a 1542 without a Bios.

Therefor since I boot of of an IDE drive and use two scsi harddrives and an RCD5020 CD-R all I needed to do was to tell LILO (which is on the IDE drive) that a 1542 existed at a particular address and interupt and viola.

This of course will not work if you have to boot from a scsi drive. Nothing will work if you must boot from or rather with a cp card as the card does not exist until software drivers are loaded.  Mileage invarient.

Not from experience, but from the grapevine,
turn off all translation and extended services of the adaptec card. If
you can, disable the PnP mode. then try again.

You may also find that you actually have to use the DIP switch settings
to disable the PnP mode.

I tried in the BIOS setup, with a Pentium motherboard, without success,
until I set the DIP switch to disable PnP mode, and disabled 1) support
for more than two drives, 2) support for drives > 1Gb and 3) BIOS scan
for ...

Hope this can help
