i386 isa drivers that used to be order sensitive. The probe order of
those drivers is now determined by a list in isa_compat.c and config
file order is totally irrelevant.
Compaq XP1000, AlphaServer DS20, AlphaServer DS10, and DP264
This has been tested *only* on XP1000's. I'll be interested to hear from
owners of other types of DEC_ST6600 alphas.
I'd like to thank Don Rice of Compaq for providing the documentation required
to support this platform on FreeBSD. I'd also like to thank Doug Rabson for newbus,
and for helping me get a multiple hoses working with newbus.

Like the PNIC, we have to copy packet headers in the receive handler
because the chip will only DMA to longword aligned buffers.
Also do some mindor cleanups.

sample cards check out.) Update the alpha GENERIC config to include
ThunderLAN driver now that I've tested it.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.
Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.
o Add the EB64PLUS systype into the kernel configuration files
and add it to the GENERIC kernel
o Correct mcclock_isa.c's dependence on cia, it should depend on isa.
This will allow avanti and eb64+ kernels to be built without the cia
chipset support code.
and dies if it can't find the MFS root whereas the x86 one seems to sail
past. Looking at the code, I can't see how either one works, so I'm
confused. :)

development and testing was done using SimOS (see

port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).
