hmmm, further reading of the data sheet makes me wonder if the serial UART is at address 2E8H for com3, if so that is disabled in GENERIC. #pccom3 at isa? port 0x2e8 irq 9 # (conflicts with some video cards)
I'm not completely familiar with the device scan when the kernel is loaded. Will it discover a device hanging off isa0 if a driver is not
compiled into the kernel and show it as "not configured" or will it just not find it at all? diana
