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, -- Ludovic DROLEZ
