Better only buy motherboards with RS232. Some brands of consumer motherboa= rds still have 1 port as standard in most models. Configuration may be as difficult in the kernel as in boot2sio. Next, try a PCI serial card. These are still relatively easy to find at a cost of less than a motherboard. Motherboards with PCI slots are becoming hard to find. (I almost bought a Z87 one with some PCI slots. 3 months later, Z87 is mostly replaced by Z97 and the PCI slots are mostly gone.) Next, try a PCIe serial card. These are not so easy to find. >> If the legacy USB keyboard route doesn=92t work out, I have a USB to PS/= 2 converter coming in the mail. >> >> It would be nice if bug 133989 was fixed.

I have one that does work with the keyboard+mouse that it came with. Apparently, doing the conversion correctly takes a lot of hardware but incorrect conversions with less hardware sometimes work, an specialized ones can cut the right corners. Just having the possibility of a useful conversion requires a PS/2 port on the motherboard. These seem to be about as standard as 1 serial port. But keyboards with PS/2 are already hard to find.
