Linux normal and extended VGA text video modes will produce a gap at the top and bottom of the screen, when used with the LTE Lite 4/25E. The correct 80x34 VGA text mode (video mode 5) can either be set at boot time using LILO, or by using rdev or vidmode to set the video mode in the kernel. You may have to experiment to find the correct video mode with the other Compaq LTE models.
The video mode can also be set using the SVGATextMode utility. Read the documentation and change the default text mode in /etc/TextConfig
#DefaultMode "80x25"
DefaultMode "80x34x8"
SVGATextMode is included with many Linux distributions. It can be found in the admin section of the Debian distribution or you can download the source from tsx-11.mit.edu or sunsite.unc.edu.
The LTE Lite base memory is 4MB, but the plug in memory cards allow up to 20MB to be used. If you have a total of 20MB, then Linux will not detect this automatically. You will need to pass the correct value to the kernel at boot time.
The following LILO configuration file, sets the correct video mode and lets the kernel see all 20MB of memory.
# sample /etc/lilo.conf
# LILO configuration file
boot=/dev/hda3
root=/dev/hda3
compact
install=/boot/boot.b
map=/boot/map
delay=50
image=/boot/vmlinuz
label=Linux
append="mem=20M"
read-only
vga=5
other=/dev/hda1
label=DOS
table=/dev/hda
Please note: make sure that you really do have 20MB before you use this example. Add the append="mem=20M" to your lilo.conf at your own risk. Bad things can happen if the kernel thinks you have more memory than can actually be accessed.
