Currently in the LPC/firmware hub form factor I have seen chips as large as 8mbit == 1MByte. And theoretical limit is something like 4GB. So as larger flash chips become available we can use them. > It is quite possible to get LinuxBIOS and a loader such as Etherboot into > a conventional flash.

Actually there is already a floppy driver in etherboot, though it could probably use some stabilizing. Only a CDROM drive requires some real work.
