Linux hang on boot (fwd)

I was trying to upgrade the mother board on my system. I have an older
P100 ami bios mother board.

I have a buslogic Flashpoint controller with three harddrives
Drive one is my boot drive Maxtor LXT340X scsi revision one.
Drive two is Quantum 730S scsi revision 2
Drive three is a Micropolis 4421-07 scsi revision 2

I also have a scsi cdrom and a scsi tape on the buslogic controller.

I have a floppy drive, pci video card and a ne2000 network card.

I am running Redhat 2 with kernel 2.0.33.

I tried to upgrade this to a Tyan Tomcat IV 5164S witha 233 MMX Pentium
processor.

I disabled the onboard IDE controller and set the bios to boot scsi

Linux loads and boots to approximately the same place every time and then
hangs.

The problems start after the message:

"mounting root filesystem read/write."B

Next init loads version 2.4 something
sometimes init hangs

sometimes the boot contines to:
"remounting root filesystem read/write"
and then hangs.

rarely it proceeds to mounting each of the hard drives and their partions
and then hangs.

I have tried a zillion different bios settings on the Tomcat IV
motherboard (ie different delays, shadowing etc) but none of this seems to
affect the point at which the sytem hangs (I rebooted so many times I
thought I was running Win95). The only way to reboot was to hit the
reset switch.

I also purchased a TYAN Tahoe PII 233 mhz for a different machine. This
mother board boots the same system just fine. Putting the old mother
board back in also works just fine. ONLY the Tomcat IV fails to complete
the boot process.

Can anyone give me a clue what might be the problem with the Tomcat IV ?

thanks
