Howdy!

    I'm trying to setup my new computer with Linux, and I'm having trouble
getting the initial Boot sequence to work with my Adaptec AHA-2940 SCSI
adapter (Ie, I insert the Boot disk used in installing linux, and either
enter nothing at the boot prompt, or one of the following lines:

         ramdisk aha2940=0x340,11,7,1
         ramdisk aha294x=0x340,11,7,1
         ramdisk aha2940w=0x340,11,7,1

and I get 0 hosts detected). Trying the following line:

         ramdisk aha152x=0x340,11,7,1

results in:

         <all lines up to FDC 0 is a post-1991 82077...>
         aha152x: processing comandline: portbase 0x340 fails probe
         Kernel panic: aha152x panics in line 613
         In swapper task - not syncing

And then it locks solid. I've verified that 0x340,11 and 7 are the right
parameters, and changing the portbase to 0x140 gives the same result. Both
the disks on the machine are on a SCSI bus, so I don't have the option of
installing on a IDE drive first and then fighting it from there. Any 
suggestions? Thanks!

             -Tom
