Hello,

I'm currently trying to install 386BSD on a machine with
the following main hardware features:

      Motherboard .......... Madex EISA i486DX/50 286 AMI-BIOS
      Memory ............... 32 MB (8 x 4MB)
      Host-Adapter ......... Adaptec AHA-1742A (Standard Mode)
      Harddisk ............. DEC DSP3105S (1050 MB)

I want to run 386BSD as on all other machines I already installed it,
but the SCSI-Drive hates me :-(. All other machines I installed via
the DIST.FS and FIXIT.FS (0.1pk0.2.3) floppy disks. For this machine
I need SCSI-support, so I tried

- the usal 386BSD DISK.FS
  This one didn't find my AHA-Adapter correctly.

- the 386BSD kernal-copy-disk from agate
  This one panics after kernal load!

- the NetBSD kernel-copy-disk (KC-AHA.FS) from agate
  This one works fine, it supports the SCSI drive and I am
  able to start the INSTALL1.FS disk. After partitioning
  the SCSI drive with the partition parameters (I want 5
  partitions: /, /var, /usr, /opt and /home) the install
  script begins with making a newfs for each partition.
  After the 3 (allways after the third!) partition, I get

  vm_fault(fe2c3200, 81931000, 1, 0) -> 1
    type c, code fe860000
  trap type 12 code = fe860000 eip = fe04f028 cs = fe860008 eflags= 10246 cr2 819
  31...

  and the machine stops! If I tried to select only 2
  partitions I didn't get such a trap! I have also
  tried both translated and untranslated harddisk
  parameter (I think translated params for disklabel
  is correct, isn't it?), but the same effect.

  What can I do?  This machine runs pretty well under DOS with this
hardware configuration and all I want now is to use the whole harddisk
for 386BSD (or NetBSD, but I will decide later) with a partition-table
of

Device     Size     Mounted On
---------- -------- -----------
/dev/sd0a     15 MB /
/dev/sd0b     70 MB <swap>
/dev/sd0c   <whole 386bsd partition>
/dev/sd0d   <whole physical harddisk>
/dev/sd0e    130 MB /var
/dev/sd0f    250 MB /usr
/dev/sd0g    250 MB /opt
/dev/sd0h    330 MB /home

  Was anyone successful with such a configuration?  Especially did
anyone managed to run the AHA-1742A successfully?  And if yes, HOW HAVE
YOU DONE IT?

Thanks for replies and followups in advance!
