I brought in a Supermicro P6DLF for evaluation because it is the
only AT form factor PII board I could find and I have a bunch of
AT for factor rack mount machines I would like to upgrade.
Both of these boards use the 440LX chipset.
P6DLF problems:
1) Can not disable keyboard checks, stupid AMI bios.
2) Sometimes refuses to boot after a BIOS config change.
3) Did not work with SDRAM. AMI's cheezy memory test ran but it
would go no further. Same SDRAM works fine in two other MB's.
4) Stream reports only 90MB/Sec Copy, PII 233.
5) mptable reports all interrupts assigned to ISA bus.
I hacked the correct PCI interrupts into an SMP kernel and got this
beast to run but I won't be keeping it.
The Giga-Byte 686DLX was plug-and-play.

I also have a Giga-Byte 686BLX. Its a single PII, 440LX chipset,
AT form factor. make buildworld with the same disks and SDRAM was
1:55. dd and stream reports are essentially the same as the 686DLX.
