I tried something.  On a board with Phoenix BIOS and Legacy USB support 
enabled, I plugged both a USB kbd and a PS/2 kbd and booted up.  I pressed up 
and down on the USB kbd but grub didn't respond until i pressed another key on 
the PS/2 keyboard and i noticed that the highlighted kernel on the grub screen 
changed according to up/down keypresses on the USB kbd, as if the keyboard 
buffer was finally processed. perhaps there's something about the interrupt 
handling in the bios or grub?

Summary:  No support for USB KeyBoards !!

Original Submission:  When configuring GRUB with an USB keyboard, i'm enable to 
select the OS I want to boot, since the keyboard doesn't work at all. (after 
booting, in linux, or windows, this is ok)

Lots of people seem to have this problem. I didn't found solutions on the net.

Thanks by advance for your help.

some BIOSes have an option to enable legacy support for usb keyboards.  Would 
this allow grub to recognize a usb keyboard.  I know this post is mainly about 
non-legacy support but this might be a fix....

Sorry for the delay of testing. I get married and started a new job ... my 
apologize.

Just to say that you may close the bug, the patch below worked  for me :

http://mail.gnu.org/pipermail/bug-grub/2002-May/007203.html

Still, could you update the gentoo distribution with this patch, or should I do 
it for you ?

The A20 patch works for me, as well. We will still need to get some sort of usb 
support natively, though. Is is possible to fit enough usb support into grub to 
get keyboard support?

my bios has a dos usb function and it makes my usb keyboard to work in grub, 
but it also makes my usb mouse to cause an oops in the kernel so its no really 
useful

BIOSes that don't do A20 right appear to be real common and since many newer 
computers only have a USB keyboard this needs to be given the highest priority. 
 There was a patch posted to the mailing list that dealt with the A20 and USB 
problem, what is the status of that patch?

Just wanted to add "me too".  I am having this problem on a Abit NV7m 
motherboard, running the latest bios: 6Q. 

thanks

Here's my config:

IBM Netvista (a "Tower" computer)

with Phoenix BIOS 4.0 Release 6.0 for IBM Netvista.

I've got an USB Keyboard connected (only, this, no other keyboard).

Using LILO, i don't have the problem.



I can try stuffs if you want (and if i don't completly loose my MBR ;)

Yes my BIOS supports USB keyboards ! And i've checked everything in the bios 
(it's a pretty cool one) and everything seems to be ok...

Perhaps USB support isn't simply implemented in grub ??

Does your BIOS support a USB keyboard?
