Mike answered: But it's the grub that loads initrd and linux kernel is actually the one using it, not the grub, so you won't get it until you drop out from grub already. Gack... I can't seem to get it straight how it all loads but I see immediately what you are saying... You can try updating grub itself though, 0.X tree ebuilds are accessible for both stable and unstable gentoo arch, but there's 1.X and even live ebuild masked in the portage tree, prehaps they would be able to work with newer hardware? I'll look into this. I also wonder, does BIOS recognize this KVM, can you access it? How would I access it?

How would I access it? Usually via DEL or F2 keys on boot, as soon as monitor lights up. Look out for message on the bottom of splash or text screen like press DEL to enter BIOS, it's there usually displayed somewhere. If not, I guess it should be described in the manual for the motherboard, which should be easily accessible on vendor's site, provided you know the model (at least the series, since there's good chance it's the same for all of them). -- Mike Kazantsev // fraggod.net signature.asc Description: PGP signature

My KVM is slightly clever, in that (boastnot only can I access it with a web-browser/boast) it allows keyboard shortcut combinations to be mapped. I have one that presses Escape, F1, F2, F8, F10 then Delete in immediate succession, and have never known this not to access the BIOS. Stroller.

But linux kernel isn't loaded or used in any way when grub screen comes up - grub is loading it as a last step of it's execution, so any kernel configuration settings should be completely irrelevant here. Ha... now I remember someone saying that when I posted about this quite some time ago. Here is the thing though. There was a time when my KVM switch was recognized at the grub boot prompt. So something has changed. Are you suggesting something inside grub can be tweaked? I've mentioned that I changed KVM switches, but with the new one, it does work by the time the login prompt comes up. So if I could identify what it is in the kernel that allowes it to work at the point where the kernel takes over (login prompt), then maybe I could enable that aspect somehow inside an initramfs, and be able to have the KVM recognized at the grub prompt by booting with an initrd.
