I have recently upgraded from 2.0.2 to 2.2 and found that the 2.2 kernel
with SCSI support built in will not boot. My configuration is as follows:
Primary DTC 7280 1:1 MFM ST506 controller with ST4096 Seagate 80M drive.
Secondary Adaptec 1542B SCSI controller with Wren V 660M drive set up as
According to the /etc/conf/kconfig.d/hpddinfo file:
The HPDD configuration selected is as follows:
Standard AT controller
Number of disk drives: 2 (maximum supported)
Interrupt Vector: 14
SCSI controller: Adaptec AHA-1540,154XA,1640
Number of disk drives: 4 (maximum supported)
Interrupt Vector: 11
RAM disk: none
THIS EXACT CONFIGURATION WAS WORKING BEFORE I UPGRADED TO 2.2! The only
reason for upgrading was the addition of an Exabyte 8mm tape drive (which
I still haven't connected yet).
In previous articles, people have talked about hardware conflicts, however
according to the controller documentation I have, there are no IRQ, DMA,
or port address overlaps. I have the floppy controller on the SCSI controller
disabled (as I did under 2.0.2).
It's hard to believe that this configuration doesn't work. Certainly there
must be lots of people with the same controller mix. My motherboard is a
Dyna SX/386-20 and along with both controllers is listed in ISC's list of
Anyone who has this configuration working under 2.2 please let me know how
you did it. ISC people - I would be willing to beta test a version of the
driver that works!

any hints ( or beta versions ;-) ).
