I wanted to try linuxbios on my computer and read on your homepage that
only DiskOnChip Millennium is supported.
WOW, how did you infer that from the web page? I need to change it if it
says something like that.

what about this. Build a composite timer with the top X bits coming from
TSC, and the bottom Y bits coming from the time-of-day counter. Would that
work?

OK, I finally read this in detail and I'm sorry for my noise on this
subject.
I think it would be useful to keep an 'emulated instruction count' in the
emulator, and have a virtual timer that increments very X (pick a number)
instructions. X can be constant across different architectures as
with the fuctory bios in place, make sure that your minicom setup is
right. Let me know.
