Re: kernel sources for alpha? (Re: Not detecting SCSI drive)
A bit more info on the problem. Here the /proc/scsi/ncr53c8xx/0
and selected dmesg output from a 2.0.30 kernel that detects the
disk correctly:
/proc/scsi/ncr53c8xx/0
General information:
Chip NCR53C875, device id 0xf, revision id 0x4
IO port address 0x9800, IRQ number 19
Synchronous period factor 12, max commands per lun 4
Profiling information:
num_trans = 4245
num_kbytes = 18818
num_disc = 5185
num_break = 83
num_int = 114
num_fly = 4245
ms_setup = 462
ms_data = 3536
ms_disc = 21080
ms_post = 211

Here's the same from the 2.2.12 kernel that _doesn't_ detect the
disk:

Looks like perhaps I should turn off Symbios NVRAM detection and
try again?
README.ncr53c8xx says to pass the argument `ncr53c8xx=nvram:n' at
the LILO prompt. Does MILO work the same way?
Thanks,
