I am looking at the latest /dev/bios code and it occured to me,
rather than swapping chips with the power on, couldn't any PCI
card with a 32pin flash socket be used instead? Even an ISA one
could be used. I have an intel 8/16 bit ISA ethernet with such a
socket,
as well as a Tulip based PCI ethernet card.
Also, aside from requiring a card plugged into board (not feasible on
1U rack systems), it would allow switching to protected mode from the
factory 128kB flash part, simultaneously accessing the DOC. (PCI
setup would be required if ROM is on PCI card)
Also, aren't there DOC's that fit in DIMM sockets? Same approach should
be possible. (leave factory flash part in) Then there's no IPL size
limit.
