ah, well, we shouldn't really do that until we resolve the VGA bios question. Looks, however, looke tehre is a bug ... Takeshi can perhaps address it better than I. I did look at our three options today: emulation, ADLO, and VGABIOS. VGABIOS is almost 100% C save for the 32-16 trampoline code. ADLO rombios.c is mostly assembly code with C wrappers around it. Emulation is C. Emulation is 256K ADLO is 64K. VGABIOS is much less, something like 16K last time I built it. The functions that VGABIOS needs to finish up to have as complete support as bringing up graphics as ADLO are not that many in number. Which makes sense: what a VGA BIOS needs to do is diddle its own registers, so most BISO functionality is not that useful for them. ADLO will not find the option rom on a card and use it; VGABIOS will. The most portable long-term way to go is emulation. I don't have room. These are the issues I have seen so far. ron _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
