This program sets the VGA Vertical Display End register to the proper value.
This problem is at least present in the BIOS of most Cirrus Logic 542x based cards, and some WD90C03x based cards.
The LINES environment variable is used to detect 43 or 44 line consoles.
fix132x43 does not usually provide this option but it can be enabled in the source of fix132x43.
This utility is part of svgalib and can be found in the utils/ subdirectory of the original svgalib distribution. However, it is not installed by default, s.t. it is unclear where you can find it if your svgalib was install linux distribution.
In case of any such problem, simply get an svgalib distribution from the net. You don't need to install it. Just make in the utils/ subdirecty. As of this writing, svgalib-1.2.12.tar.gz is the latest version and can be retrieved by ftp from sunsite.unc.edu at /pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs which will most probably be mirrored by a site close to you.
This manual page was edited by Michael Weller <firstname.lastname@example.org>. The exact source of the referenced utility as well as of the original documentation is unknown.
It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
