I'm running Debian (kernel 2.4.21) on a Dell Optiplex GX Pro and know just enough to be very dangerous.
The disk seemed a bit sluggish, so after a little research, I tried turning on DMA on the boot drive with:
hdparm -d1 /dev/hda
Things were OK immediately afterwards. hdparm -Tt showed a 50% improvement. I made happy noises.
Shutdown and now won't boot. After BIOS messages, it sits at a text-mode GRUB message (not a prompt - system is unresponsive; not the GRUB menu - just the words GRUB).
This system won't boot from floppy or CD, so I'm hosed.
Hoping to recover all the filesystems on the disk. I was thinking I would pop the drive into another machine running the same distro and try doing a grub-install.
Good idea? If not, any other suggestions?
Will the drive "remember" it's set to DMA?
Thanks in advance for any advice!
