Hi !
Recently I tried to use grub(2) with a compaq evo D510. These boxes do not seem
to have a keyboard controller, so grub freeze in gatea20().
Most free bootloaders fail, but one is okay: syslinux/isolinux.
I've taken a look at syslinux's code, and indeed A20 activation is done much
more carefully than in grub, and more tricks are used.
I think it's really important to fix grub's code (by stealing code from isolinux
?), because more and more PCs without a good old keyboard controller will hit
the market.
Are there any plans to improve gatea20() ? (Moreover, grub2's code for gatea20
is even worse than grub-legacy)
Regards,
