AIC-7770 on motherboard (~Adaptec 274x?)

Post by Ken Neighbo » Mon, 14 Nov 1994 08:19:17



I'm trying to install Linux on a Pentium system that has an AIC-7770
on the motherboard.  I made the 1.1.62 kernel with Adaptec 2[78]4x
support (on another system), and created a Slackware boot disk with
it.  When I boot off this disk, I get:

aha274x warning: ignoring channel B of 274x-twin
aha274x: extended translation disabled
AHA274X AT EISA SLOT 9:
    irq 11
    bus release time 60 bclks
    data fifo threshold 100%
    SCSI CHANNEL A:
        scsi id 7
        scsi bus parity check enabled
        scsi selection timeout 256 ms
        scsi bus reset at power-on enabled
        scsi bus termination disabled
scsi0 : Adaptex AHA274x/284x (EISA/VL-bus -> Fast SCSI) 1.28/1.11/1.29
scsi : 1 hosts.
(hangs)

I tried a kernel with and without network support for the ethernet
card 3c509, and I also tried the 1.1.54 Slackware scsi boot kernel.
They all say the same thing (but different version numbers).

I'm a little concerned about the "termination disabled" message, but
according to the documentation that came with the computer, it's
terminated properly, and MS-DOG has no trouble booting up and seeing
the hard disk (a 2GB Seagate barracuda).

The only response I got was a few "me toos".  Who is actually working
on this driver?  I don't understand why some people have got it
working but not me--I tried kernel 1.1.64.  Perhaps something is a
little different when the AIC chip is on the motherboard?

I'm wondering if I should keep waiting or give up and buy a better
supported network card.

AIC-7770 on motherboard (~Adaptec 274x?)

Aiming at Linux on a CompuAdd 486-66DX2 system with SCSI support via
an AIC-7770 embeeded into the motherboard.  
Getting the following during the boot sequence.

calibrating delay loop ... ok - 33.55 BogoMips
aha274x warning: ignoring channel B of 274x-twin       >OK, HDs and CDROM
AHA274X AT EISA SLOT 9:                                >on Channel A
    irq 11
    bus release time 60 bclks
    data fifo threshold 100%
    SCSI CHANNEL A:
        scsi id 7
        scsi bus parity check enabled
        scsi selection timeout 256 ms
        scsi bus reset at power-on enabled
        scsi bus termination disabled
scsi0 : Adaptex AHA274x/284x (EISA/VL-bus -> Fast SCSI) 1.26/1.11/1.28
scsi : 1 hosts.

(hangs)

Another oddity, maybe, is that when booting the Slackware 2.0.1 SCSI bootdsk
boot floppy I get a message about:

"Uncompressing Linux ... memory is tight ... done."

When booting the standard floppy, I don't get this message.
Of course, it doesn't see the SCSI ADpater either.

I don't know about the SlotCard based Adaptec SCSI Adpaters, but there
is a BIOS based parameter for turning on/off the Channel A/B
termination on the SCSI Adapter.  There are no physical terminators on
the motherboard.

More information:
From the EISA Configuration Utility

Slot 9 - Adaptec AIC-7770 SCSI Host Adapter
 Host Adapter Interface Definitions
  Interrupt Level...................... IRQ 11 LEVEL
  Bus Release Time..................... 60 BCLKS
  Data FIFO Threshold.................. 100%

 SCSI Channel A Configuration
  SCSI Channel Interface............... Dual Channel, Single Ended SCSI
  Host Adapter SCSI ID................. 7
  SCSI Bus Parity Check................ Enabled
  Selection Timeout.................... 256 milliseconds
  SCSI Bus Reset at Power-on........... Enabled
 SCSI Channel B Configuration
  Host Adapter SCSI ID................. 7
  SCSI Bus Parity Check................ Enabled
  Selection Timeout.................... 256 milliseconds
  SCSI Bus Reset at Power-on........... Enabled
 Primary Channel Selection............. A
 BIOS and Device configuration......... Press <Enter> to Configure

And when entering the BIOS Configuration:

 Support Removable Disks as Fixed Disk......... Disabled
                                                Boot Device Only
                                                All Deviecs       <<<Selected

 Extended Translation for Drives > 1GByte...... Disabled
                                                Enabled           <<<Selected

 Support More than two drives.................. Disabled
                                                Enabled           <<<Selected

All in all this setup seems to work quite nicely in MS-DOS and OS/2 Warp.

I would appreciate any pointers.  Somehow the chip-on-board seems to
have a slightly different implementation than when planted on a board
which goes into a EISA or VL-bus slot.

When reading the manual that came with the 2742T's in my NetWare server,
it recommended turning this off for OS's that didn't have DOS's limitation
on drive size (i.e. NetWare, Unix, etc.)

Don't know if this is causing your problem, but it could save you
heartaches down the road.

Subject: Re: 7770 on motherboard

Has anyone out there gotten Linux to boot successfully on a machine
with an AIC-7770 controller embedded in the motherboard ?

If so, please mail a note so I can find out why I have been singularly unsucessful.

Thanks.

1. Adaptec EISA AIC-7770 HELP!


I have exactly the same problem with a 486 EISA Board. I tried other
Linux Distribution (the german LST 1.8 and Slackware 2.0.0) with the result,
that the SCSI host adapter was completely ignored by the bootdisk (SCSI
hosts: 0).

So if anyone has an idea please help!
