Re: [gentoo-user] Install a 64bit system from a 32bit minimal CD

[Yoav Luft]

Well, seems like the other PC's cd writer got mildly broken so it can only
read cds, not burn any. So after some thought, I salvaged my old PC's cd
writer and installed it (in quite an ugly way, as ide cables were to short)
in the windows box, burnt the LiveCD and installed Linux on my new machine.
I just booted it up for the first time, and it looks... ok. I think I forgot
to include vesa or other standart video support in the kernel.
