Why Cant I boot from built in VGA motherboard

After installing the Linux in a computer with VGA built in mother boards, the LILO starts but fails before completing the startup. The computer freezes...

The reason for it is that the memory shared by the computer with the SVGA built in the motherboard has not been specified properly.

To rectify the error..
WHEN the LILO appears when the computer starts.. type in the following

linux mem=xxxM

where xxx stands for the actual memory in MB available after the vga allocation. You replace this figure with the memory available in your system. Note the upper and lower casings carefully and M stands for Megabytes of memory.

After the bootup...
edit the lilo.conf in the etc\ directory using pico or vi or whatever way... add the line
append = "mem=xxxM"
where xxx is your memory available in MB after the VGA share as per BIOS setup. After the saving of the file
run /sbin/lilo -v

This shall permanently send this configuration for lilo booting.
