5.2 install/upgrade X config change?

So, I went to upgrade from 5.1 x86_64 to 5.2 using the DVD and just at the point it switches to X to display the graphics for asking the install questions my monitor goes blank with: "input signal out of range" This worked fine on 5.1 install with same monitor, a wide-screen HP f2105. Any way to fix...

Re: grub hangs in stage 1.5

Super grub doesn't help. Choosing "GRUB => MRB & !LINUX! (1)" can't find /grub/stage1 or /boot/grub/stage1 Choosing "Coose Language", oddly enough, gets me into the grub prompt but the "initrd /initrd-2.6.18-53.el5.img" command (after "kernel...") causes an error saying there is not enough memory, a...

Re: grub hangs in stage 1.5

Yes, you were right! The BIOS must be choosing /dev/sdb1, (hd1). However, now I REALLY do have the problem mentioned in: http://www.nabble.com/fixing-the-%22grub-loading-stage1.5%22-hanging-error-td13434214.html With stage1.5: the "GRUB loading, please wait..." hang. Removing stage1.5: the "GRUB" ha...

Re: grub hangs in stage 1.5

My guess was that it would only boot off of one drive, because at that point
the other disk looks like any other secondary disk since RAID is software (md) .

grub hangs in stage 1.5

I'm trying to get grub to work on a x86_64 5.1 system with md RAID 1 disks. I did: grub-install /dev/sda1 grub > root (hd0,0) > setup (hd0) on reboot it hangs at "loading stage1.5". I followed this (and "setup" does indeed not find stage1.5 file) but still hangs there: http://www.nabble.com/fixing-t...

Re: "linux rescue" broken

OK, still having grub problems, but at least I can get a rescue shell.

Thanks all for the "rescue" help.

Re: "linux rescue" broken

Ah...reading more of the rescue web page, "fdisk -l" yields:

Disk /dev/sda: ....
/dev/sda1 (boot)
/dev/sda2

Disk /dev/sdb: ....
/dev/sdb1 (boot)
/dev/sdb2

I assume I need to fix both, but how to fix?

Re: "linux rescue" broken

No, I did not skip! And, I just tried skipping and it put me into the shell, great! Er,...now what? :-) Following this: http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/custom-guide/rescuemode.html I did: [b]mount -t ext3 /dev/sda1 /foo[/b] and can read the disk and see the grub directory in ...

Re: "linux rescue" broken

The RAID controller is in software (no hardware board). My guess is this is the problem. Still don't know what the solution is, or even if there is any. I would be more than willing to install a hardware controller if it would allow me to read the disks, at the least, allow future rescues and maybe ...
