[gentoo-user] Re: Grub problems

[Jeff Cranmer <jcranmer01@earthlink.net>]

Update.

After a little bit of surfing, I tried the command grub-install --recheck /dev/sda
That changed the device map file so that the /dev/sda drive mapped to hd2

The full /boot/grub/device.map listing is now
(fd0)   /dev/fd0
(hd0)  /dev/hde
(hd1)  /dev/hdh
(hd2)  /dev/sda

I edited the grub.conf file so that the splash image and root lines reference (hd2,5), then re-ran grub-install /dev/sda.  Still no joy.  On boot up, the screen stays blank for a while, then every 10 seconds or so, it adds another " GRUB" text element to the screen.  No sign of any boot-up activity.
