- Most serial port redirection bios, once enabled, causes the uart
- in question to disappear and become unavailable to the host
- OS, hence requiring you to have 2 console cables, one for the BIOS
- and one for the OS.

- At least that's been my experience.
Well, NetBSD sees both the serial ports once it's
booted. And FreeBSD seems to be able to cope with it..
- There are other hardware devices that can solve this problem for
- you.
Yeah, I've got four weasel's aready. I just hate
loosing my sole PCI slot in these 1U boxes to the Weseal (I'd
rather drop a FC host adapter in there..)
If that ends up being the case, I'll have to harrass
Greg D about upgrading my three ISA/MDA Weasels.
Thanks,
Eric
