Dual PII 300 on a PCChips motherboard, Adaptec UW SCSI (IDE disabled at bios) 512 Mb ECC DIMM... I have also tried with IDE enabled in BIOS... My compiled 2.2.1 seems to work fine with source from kernel.org and IDE support disabled, but the source from the kernel source RPM (this is on -2 and -3 RPMs) will not build... Stock SMP and regular kernels blank screen and halt system almost immediately on boot... Too soon to leave any clues in log files...
Probably you need a LILO compiled with large EBDA support. A LILO compiled for large EBDA support will most likely break "normal machines", so we are waiting for a patch from the author.
