USB Keyboard not responding in grub bootup
Last modified: 2008-05-01 11:38:01 EDT
Description of Problem:
The grub bootscreen doesn't accept any input from an USB Keyboard (can't
select kernel or enter Options). While LILO takes all input correctly
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install grub
3. try to choose from kernels
only boots the first kernel in list
ability to choose the kernel / OS on bootup
grub is configured as password protected but wouldn't react on pressing the p
This is odd as GRUB and LILO both apparently use the same BIOS calls to get
keyboard input. What type of hardware is this on? (as I haven't seen it on mine)
This is on a Fujitsu-Siemens Jetson Computer. i815 Solano (FSC D1189) board
with a Celeron 700. It4s the standard FSC USB Keyboard attached. 82801AA USB-
Hub. If it helps, the system is profiled as System ID 1000408856 in the RHN.
I have gotten some support requests indicating this problem also exists on some
HP Pavilion machines.
Tested grub with USB keyboard on an IBM Eserver model X series 200 and it worked
Tested both Grub and lilo with a USB keyboard on a Dell Precision 420 and the
USB keyboard did not work in either one, nor the BIOS, but it works fine once
linux boots.. so evidently this machine has no bios emulation for USB keyboards.
to be more confusing: BIOS works, and LILO prompt works too... so the emulation
is working as expected, i suppose. is there anything for interrupthandling in
the grub code, that isn4t in lilo4s? sorry i4m no coder, so i can4t check for
Don't know if this is related or not...
After switching from lilo to grub with RH 7.2, my USB mouse is no longer
recognized by Windows 98. Linux sees the mouse with no problem. With lilo both
W98 and linux see the mouse. With grub, if I switch to a PS/2 mouse, both
Windows and linux see the mouse. The mouse is a Microsoft Optical Wheel Mouse,
and my motherboard is an Intel SE440BX (Phoenix BIOS).
I'm having the same problem on a Gateway Performance using a the SUN
UNIX USB keyboard. LILO works, grub does not. Keyboard works after USB loaded.
Same thing happens regardless of whether legacy USB support is enabled or
disabled in the BIOS.
Like I've said, none of my hardware reproduces this... you might try installing
the updated package at http://people.redhat.com/~katzj/grub/ and then running
`/sbin/grub-install /where/you/installed/grub` (eg /dev/hda) and see if that
makes it work.
