the system does not take up the entire screen and appears to work in 600X800
what does it mean?
maybe 640x480 or standard VGA...
If your video board support VESA protocol (see your board documentation) you can try something like this:
* If your distro use LILO as boot loader:
at boot time go to LILO command-line mode (hold the <Alt> or <Shift> key before the ``LILO'' message appears)
and type vga=318
then press enter
you should see the boot sequence in 1024x768 32M colors.
If it work you can add this option in the LILO configuration file
(/etc/lilo.conf) at the end of the line boot= <blah blah blah>
Don`t forget to run LILO *every* time you modify lilo.conf file (simply type lilo).
I don`t use LILO as boot loader so i am not 100% sure that these are the right steps.
See LILO documentation and HOWTOs.
* If your distro use GRUB as boot loader:
The steps are similar,
at the GRUB boot menu select the Linux and kernel you want to boot
type 'e' to edit the command-line and ad vga=318
then press enter.
As above if it work you can add this option to the GRUB configuration file
(usually /boot/grub/grub.conf or /boot/grub/menu.lst).
You DON'T need to run GRUB to make the change permanent!!! (This is why
i use GRUB)
See GRUB documentation and HOWTOs.
You can find other VESA mode in the kernel documentation directory (i don't
remember where and the file name - i'm at work now
I hope this can help you.
P.S.: Sorry for my english!
