Hi again,
unfortunately I didn't get a lot of input on this question.
However, working my way down from the GENERIC kernel (which I was able
to compile after removing some lta* ATM controllers) I found out
that I had to add a "DECAXPPCI_33" configuration in order to get rid
of the 'io_blockread/write' errors.
To sum it up, after a plain doconfig I had to add the following lines
in order to compile a kernel which runs fine on our DEC 300 and 600:
> options MULTI_PLATFORM
> cpu "DEC3000_300"
> cpu "DEC3000_500"
> # REMARK: STUFF WE SHOULD NOT NEED BUT IS REQUIRED FOR DECAXPPCI_33
> cpu "DECAXPPCI_33"
> # Primary PCI Bus adapters
> bus pci0 at *
> callout after_c "../bin/mkdata pci"
> # Isa bus
> bus isa0 at pci0
> callout after_c "../bin/mkdata isa"
> # Terminal devices
> controller ace0 at * slot ? vector aceintr
> # PC mouse/kybd:
> controller gpc0 at * vector gpcintr
> # REMARK: END OF THAT STUFF
Why this is required remains a mystery for me - but as long as it works
...
