My board is a P2B-LS (with LAN and SCSI). I have one 20GB IDE and one 18GB SCSI disk which can both be the first disk (depending on AWARD BIOS settings). Win2K is on the first partition of my IDE disk.

I tried two different installs:
(1) With SUSE Linux on SCSI disk as first disk
(2) With SUSE Linux on IDE disk as first disk

The onboard Adaptec AIC controller was recognized during install in each case. Same for the LAN.

In install (1) I failed to get a Win2K boot with Lilo or GRUB from my (then second) IDE disk. Even the "switch disks" command in GRUB did not do the trick.

In install (2) I had both OS on one disk and it was easy to boot both systems with the GRUB bootloader. However, some partitions on my SCSI disk were not recognized by SUSE and could not be installed via Yast fdisk setup. I had to manually edit /etc/fstab, but then everything worked (and still works) fine.

Very, very stable with my PII 400.
Runs great as a webserver/firewall/router.

1x AGP, 4x PCI, 3X ISA
3x PC100 DIMM Slots (up to 768 MB)

All the drivers you could want for this board are in the kernel (and have been for years).
