For those who may be still running on such old hardware, I thought I would drop in this note to save someone some time.
It does work and seems to work pretty well with a couple of little glitches:
1. the kernel boot paramters now use the keyword memmap and not mem
memmap=exactmap memmap=640K@0k memmap=???@1m nousb
where ??? is totalram minus 1MB
2. to recognice smart-2/e raid adapater, choose smart2 driver (cpqarray) and add the driver option of eisa=0x?000 where ? = slot number reported by bios.
3. I got a scsi parity error on the ncr53c810 on every boot which stopped device mapping for cdrom and tape drive. adding rmmod sym53c8xx, modprobe sym53c8xx to rc.local fixed the problem. There is probably a more elegant solution, but this worked for me.
An issue that I have to be tackle not hardware related are the acls issue and dump. dump complains about inodes refusing to be dumped. I have SElinux loaded and maybe this is the issue?
