Hi, This isn't in the official grub sources yet, but it is very useful and as far as my system goes, it works like a treat. This is a patch written by Erich Stefan Boleyn which fixes/works-around some Gate A20 issues with stage2 of the bootloader. Specifically, this fixs problems with some BIOSes and USB Keyboards being inoperative in grub. Even though the BIOS settings indicate that the USB Keyboard support is enabled (aka. legacy mode), grub still doesn't detect it. This patch fixes this problem. I've tested it on both grub-0.90 and grub-0.92 in the portage without any problems. I just packaged it up a little and submitted it here. Cheers, Alastair
Created attachment 3023 [details, diff] patch to fix gate a20 issues works on both 0.90 and 0.92, despite file name
Alright, I've added the patch to the still masked grub-0.92.ebuild. Please reopen the bug if that's not satisfactory, and I'll consider another revision of the 0.90 ebuild. Thanks!
It would be a great idea to insert the patch that Alastair posted in the portage tree ! I guess lot's of modern computers have the USB problem... I've tested the patch based on the CVS version of grub, and it works ok.
