GRUB Problem - what is this

[Tokunbo]

hello,

I powered on my PC(RH9, dual boot with windowsXP) this morning and i get the following error message:

GRUB Version 0.93 (639 Lower / 244672K upper memory)
[Minimal BASH-like editing is supported. For the first word, TAB lists possible command completions. Anywhere else, TAB Lsts the possible completions of a device/filename

Error 18: Selected cylinder exceeds maximum supported by BIOS

I still used the PC yesterday before I had to go out for something and I had turned it off normally.

Pls how do i resolve the above error message.

Looks like something got changed in te BIOS.
When you boot up, you should see a message like,

Press XXXX to Enter Setup

Hit whatever key it tells you.
Look through the BIOS screens for how your hard drive is looked at. Change it to "Auto".

Was it set to Auto in the BIOS?
Your other option would be to use the grub commands to boot into your system.

find /boot/grub/stage1

You should get something like

root (hd0,3) ENTER

returned

The next command will be just that.

root (hdx,x) Whatever the previuos command gave you.
Next is the kernel command. You will have to use the TAB button for some of this stuff.

kernel (hdx,x) / TAB Now you will get a list of possible completions.
If the kernel name is in there, put that in. Or if boot s in there, put that in and hit ENTER.
Now comes the initrd command. If there is one in there.
Do it the same as the kernel command.
Type "boot"
