Very Computer

When I tried to install Linux on my PC, which I bought yesterday, I had
problems with my Adaptec compatible SCSI controller.
This is my setup
        AMD 486DX2 66MHz
        16 MB RAM
        Cirrus Logic VGA, 1 MB RAM, VESA Local Bus
        I/O with 1 parallel, 2 serial, 1 game port
        VESA Local Bus SCSI Controller with floppy controller
                3.5" HD disk drive (TEAC)
                500 MB SCSI drive (Quantum LPS540S)

The SCSI controller is a Adaptec clone which the manual says is
        "Fully compatible with Adaptec AHA-1522A in H/W & S/W
         (Using Adaptec's AIC-6360 SCSI chip & ASPI software family)"

All switches are set to the factory default which is:
        SW1: ON:                I/O port = 340h - 35Fh
        SW2: ON:                BIOS enable (enable boot from SCSI BIOS)
        SW3: ON,  SW4: ON:      BIOS address  DC000h
        SW5: OFF, SW6: ON:      SCSI IRQ port = 11
        ...

With debug under MSDOS I get

-d dc00:0

The controller has SCSI ID 7, the drive SCSI ID is set to 0.

When booting from the "uniboot" bootdisk of the slackware package without
giving parameters to LILO I get the following messages ( cat /proc/kmsg )

<6>Console: colour EGA+ 80x25, 8 virtual consoles
<6>Serial driver version 3.96 with no serial options enabled

cat /proc/version gives (as above)

I also tried pressing ALT to run the boot kernel with the following
commandline:

        ramdisk aha152x=0x340,11,7,1

After some messages, which look OK, I get a screenfull of the following
message:

        aha152x: more data than expected (130 bytes)

Then comes a lot of other weird (at least to me) messages and the systems
hangs.

Is there a way to get this controller to work with Linux.  Just to see
if the controller isn't damaged, I booted with a friends MSDOS boot disk,
partioned and formatted the drive, and everything went fine.

Any suggestions?

Thanx

The problem seems to be a timing problem caused by the bus being
  faster than the 20MHz clock on the 6360. It's what causes the 'more
  data than expected' error. With the patch my system is
  working fine. The driver isn't recognizing your controller because
  it's copyright string isn't built into the driver.

He also might try getting a kernel later than 14d if he's already got
linux installed.  if he doesn't have it installed, i have a 14z kernel
up and running, and if someone can tell me how to make an installation
bootdisk, i'd be more than happy to do so.
