I know it's usually not cool to respond to your own message but I have a
bit more info - I removed the old isa modem (SupraExpress 288i PNP),
rebooted and now 5.1 is installing. The old modem uses the Rockwell
chipset, maybe there's a compabibility issue here. I don't need that old
modem so rem
I am trying to install 5.1 on a old P166. The install starts then fails
with these messages -
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 8250 not responding
that is where the install is now hung.
