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?
Comment 2 John Verel 2001-11-01 11:57:00 EST
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
