SubjectProblem with NCR 53c810 driver in 2.0.10
Date
I have a 486DX4-100 motherboard (ASUS PCI/I-486SP3G) with a built-in NCR
53c810 SCSI adapter. I am trying to run Linux on this machine. When I
boot up, however, Linux crashes. I can boot this computer from a floppy
I made with kernel 2.0.7. Here is the message I get when I boot 2.0.10
from the SCSI hard drive (this is a hand typed copy of the last screenful
of information):

FDC 0 is a National Semconductor PC87306
