Very Computer

I have a dual drive, mixed SCSI/IDE system running kernel 2.0.18.  I
finally had time to get back to my linux system after a month of
firghting with NT 4.0...when I discovered this problem--no SCSI
adapter detected on bootup.  Linux used to find my BusLogic BT-948
just fine.

Since I last used Linux on this machine, I'd been struggling with a
Microtek E6 scanner installation on NT 4.0.  I did the following in
hopes of fixing the scanner problem:

        o updated buslogic firmware/BIOS from 4.95L/5.05R to
          4.96F/5.06I
        o Gave up on E6 coexisting on a real SCSI bus and installed an
          Adaptec 1502AE under NT.  When I discovered the Linux
          problem, I physically removed the 1502AE from the system (at
          first I suspected a SCSI host adapter conflict...but problem
          remains even without the 1502AE)

Since my Linux root is on the IDE drive, I can boot semi-okay...until
it tries to check the filesystem on /dev/sda3 (I have /usr mounted
here).  It reports that device /dev/sda cannot be found, and drops me
to an emergency shell asking me to fix the filesystem.  I suspect the
filesystem is fine, if only I could find /dev/sda.

        % fdisk /dev/sda

yields the same result--/dev/sda not found.  When I reboot and watch
the console messages, I see that no SCSI adapter is ever detected.

When I try to manuall insmod BusLogic.o, insmod reports that the
module installation was not successful.

Do I need an update to the BusLogic driver to support the new
firmware?  I'm currently using the driver that came with RedHat 4.0.

TIA for any advice,
Todd

Thanks for the info!

Hi todd,

Didn't redhat 4.0 ship with the 1.2.x series of kernels? The buslogic
driver in that is absolutely ancient.  I believe it still used to probe
for the ISA compatible I/O address.  The 948 series, at least in
later revisions, has the ISA port off by default. You should probably
update to redhat 5.0, or at least 4.2.  (Although that might break
other things).  Alternatively, you can just go into the
Buslogic SCSI setup program with control-B and turn on the
ISA compatible I/O port.
