really affect me because I know how to fix the problem --- it would be
nice if the patch was selectable from the kernel ``make config'' though.

Nope. The bios allows for the enabling (and disabling) "fast A20 gating"
but neither setting causes the error to go away. It fails in both cases.

guess there are not that many people with Tecra's because they are not
exactly cheap, but how many motherboards are giving the A20 problem ?
The machine I'm testing on is an old 486DX on a Trident mother board with
AMI bios from 1992, but I have seen the same failure on my more recent P75
machine, so for me the market looks like "all" non-Tecra machines fail ;-)
I would suggest providing a "tecra" kernel image along side the "linux"
image provide in the base disk set. This could be placed in a seperate
location for "special kernels" but at this point its the only one.

booted, and you don't need a 1.2 version because laptops don't have them.
It would take less space to provide the kernel image and let the user copy
it to the "standard" rescue disk.
