RE: [Linux-ia64] USB Support

I've also noticed how certain USB keyboards will hang the system (POST 80:
0x54).
If you hard reset the system, it'll get stuck on Post 80: 0xFF.

Anyways, the BIOS USB support code is broken in certain places.  It may
account for the erratic behavior I've been seeing in the EFI shell with the
USB keyboard (which in turn would affect the Turbolinux 0505 installation).

I'm interested in finding out what errors you're seeing. ELI uses the
standard Text Input protocol which EFI should handle regardless if it's
PS/2 or USB.

I'll try this as well.

Gotcha. I haven't tried this. I don't know why this wouldn't work except
for explicitily not compiling in USB for the install kernel.
