Hi, all. I'm having problems with my new, no-name ISA SCSI card with
an NCR 53c400A chip. This board is jumpered to I/O port 0x350 and IRQ 5.
When the system boots up, the SCSI BIOS correctly probes my SCSI
drive. I can correctly FDISK and FORMAT my drive under DOG (and even
boot DOG from the drive), so the controller appears to work.
However, when I boot Linux (v1.1.72 with Kevin Lentin's 53c400.patch
(version 1(beta)) file), I get the following message on bootup:
scsi0: at port 856 irq 5 options CAN_QUEUE=16 CMD_PER_LUN=2 release=1 generic
options AUTOPROBE_IRQ AUTOSENSE PSEUDO DMA generic release=6 ncr53c400 release=1
scsi0: Generic NCR5380/NCR53C400 Scsi Driver
scsi : 1 hosts.
and then the system hangs (waits forever:-/). It doesn't matter if
there is a SCSI drive on the bus or not: either way it hangs. Does
anyone have any idea what may be going wrong? I'm starting to get
desperate and considering parting with more money for an Adaptec 1522
:-(
BTW: when I type "ncr53c400=0x300,7" at the LILO prompt, the above
message (...at port 856 irq 5) does not change: I can't seem to
override these parameters (but this is not as important as getting the
controller to work under Linux:-)
Regards,
Richard....
