Great news! :-)

We will see.

I had a look at this some time ago. It looks like quite some work to
make our HIL code MI. The OpenBSD code is already MI and largely
rewitten. An import was not that hard and it worked for hp700.
Unfortunately I never came around to convert hp300 to use this code.
I'll take care of this again...

I am clueless in the VM area, all I can do is testing on a C100, J200
and K100. (All single CPU.)

To be honest: Does EISA interrest? ;-)
There is code for one of the two EISA bridges found in hp700 machines.
IIRC it was the older chip found in some PA7000 machines.

I tried (e)siop(4) and tlp(4) cards with success, even some quad tlp(4)
cards with a PCI-PCI bridge worked. An ahc(4) made problems when used in
PCI-IO mode, IIRC it worked when the ahc(4) driver was tweaked to use
PCI-MEM. fpa(4) did not work, but this is due to funky things fpa(4)
does with bus_dma(9). I can try to get some more cards for testing.

We also need to take care of sysinst...
