Description of problem:
When using the 'linux rescue' option on a Valhalla CD to repair a system, the
rescue process starts but when the blue background and text windows are meant to
be coming up, our IBM 8513 plain-VGA monitor loses sync and one has to go find a
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Take an Intel box with a IBM 8513 or other VGA-only monitor
2. Boot off Valhalla disk 1, typing 'linux rescue' into the RHL cd prompt
3. Wait for the UI to start
Actual Results: As the blue-background UI comes up, monitor shows mostly-blue
Expected Results: The monitor should have displayed a text-mode rescue disk
screen with a blue background.
This monitor works fine in bios text mode, regular text mode inside Linux
itself, and even the 320x200 Red Hat LILO boot graphic. This is the monitor we
use for our KVM switch in our server room.
I suspect a niftier text mode is being used without first probing for its
I worked around this bug by borrowing a multisync monitor. It lengthened the
downtime of the server in question from about ten minutes to about forty-five
Should be ok with Red Hat Linux 8.0 since we dont use framebuffer.
