Description of problem:
7.2 Installed on Toshiba Tecra 530 Laptop, grub splash image appears
corrupt, unreadible. Same result if image is unzipped. Workaround:
comment out splash screen in grub.conf. Result occurred in 3 of 3
Version-Release number of selected component (if applicable):
Steps to Reproduce:
3.See corrupt screen
Actual Results: Screen was mostly unreadible. Part of RedHat Logo
Expected Results: Normal splash image.
Can you verify that the image does load properly if you look at it with say the
Also, since this is a laptop LCD, is there a way to switch between stretched to
fill display when in a lower res or just using part of the screen? If so, does
switching between these make any difference?
I confirm that the image, unzipped, loads correctly with the gimp.
The BIOS for this machine has the option of using "stretch". Changing to the
stretch setting has no effect on this problem. I tried it with both the zipped
as well as an unzipped version of the image, both living in /boot/grub.
There are no other resolution settings availible in the BIOS. The BIOS is the
most recently available from Toshiba. The default color setting, which cannot
be changed, is 16 million colors.
The top half of the image is completely garbled, including the Shadow Man
image. The bottom half is readible, in particular the words Red Hat.
Same problem on Toshiba 220CDS. The splash screen itself is fine. It's the text
on top of the splash screen that is entirely corrupted. (Wrong char-set or font?)
Likewise, disabling the splash image solves the problem.
Same problem on Toshiba Tecra 730CDT.
Same on a Toshiba 440CDT. The image is fine. The text which is written on top of it is garbled

This is a BIOS bug in that it doesn't properly support the standard vga16 video mode
