AFAIK there is (officially) _no_ high-speed mode on the 701.
It's a 900 MHz Celeron _permanently_ underclocked to 630 MHz. I
remember there were some kernel module hacks to run it at 900 MHz
nevertheless, but this was IIRC quite unreliable so I stopped using it
after some tests. Can't remember the details what was bad about them,
but I still know it caused far less problems (especially not reliably
reproducable problems) than this one.

So I have at least the latest of those EeePC4G*.zip BIOSes. I'll check
later if 701-ASUS-1302.zip also applies.
