Hi!
I've got NetBSD on the Amiga-PD-1 CD from an Amiga Magazine special edition.
There's one major problem with this release (NetBSD-1.0) - it doesn't run
correctly on my hardware that consists of:
Amiga 2000, 1MB Chip, ECS, KS 3.1
A2091 with "Non-Proto" - WDxxxxx-08 - chip, Power-DMA ROM
A2065 ethernet card
Vortex GoldenGate 386SX (configured to give 4MB of the 8MB PC-RAM to the A2000)
Some ISA-Boards (don't matter here)
A2630 board with 2MB fast RAM
DKB2632 fast RAM board for the A2630 (now equipped with 4MB at $07C00000)
So my problem is that the SCSI doesn't work when I use the DKBs fast RAM.
I can read directories on the CD or on an ufs harddisk but when trying to
something else (e.g. decompressing) I get errors. ADOS fs doesn't work
at all because of that (chksum errors) - in some situations I can mount
an ADOS partition but will relatively soon get error messages.
The problem seems to be that the DKB is a non DMA board (due to the fact that
the memory (up to 112MB) is above the 16MB border...). I have tried different
kernels but the problem seems to be in the A2091 driver. The DMA mask is
$FFFFFF (told in the boot sequence) and is correct.
One solution (not a good one...) is to use the Vortex RAM (also 4MB, DMA is
possible). This works but since it's 16bit Zorro II RAM it's severely
slower than with the DKB RAM.
So does anyone have a solution or some idea to get NetBSD to work? I can't
recompile the sources until I get the binaries running :-(
Thanks in advance,
