Remove the bios emulator from MAI board.
The bios emulator in the MAI board can not pass compile
and have a lot of crap in it. remove it and will have a
clean and small bios emulator in the drivers directory
which can be uesed for every board.

Elsa Victory II-A16 AGP Banshee -This card is very clever: It knows it is an AGP card. Therefore -it knows it is behind a PCI-PCI bridge. It also knows that noone -else is behind this bridge. Therefore it start reprogramming the -bridge! For this it assumes the AGP bridge is on bus 1. - -4. Elsa Gloria Synergy 8 ViVo AGP PM2 -This card likes to see a complete interrupt vector table.

It wants -to read the system BIOS date at 0xffffd. - -6. Matrox Mystique PCI -This card reads the IO port 0x62. If it doesn't like what it sees -it loops forever. To keep the card happy put 0xfc into 0xffffe. -This location holds the system model id. 0xfc means IBM-AT. - One can make an interesting observation: this card likes to know -with whom it has to share the system. Therefore it accesses PCI -config space of all the other cards. It does this bypassing the -PCI BIOS by reading the PCI access ports directly. - -7. Matrox G100 AGP -This card has the same problem as the Mystique. - -Apperantly this works now. However not all combinations of cards are -checked, yet. - -Further notes: -the IO register 0x42-0x43 as well as 0x61-0x63 are of special interest -for many graphic cards. They should be emulated. -The so called "Industry Standard BIOS Entry Points" to int 0x42 (0xFF065) -and to int 0x1a (0xFFE6E) should be filled with useful code. This code -needs to return as if it was called as int. -The subvendor ID PCI registers might cause problems. On some chipsets -they are programmed in a non-obivous non-PCI conformant way. -V_Bioses are seen to modify the following int: -0x10 (default video), 0x1f(font table), 0x42(copy of default video), -0x43 (??), 0x6d (copy of default video - same as 0x10?) - -TODO: -Int 0x6d needs to be done. -All interrupts where there is no default industry standard entry point -should point to an unused location in the 0xF000 segmant (possibly -0xF0000). This way they could be trapped. A trap handler for -a. int 0x42 and int 0x1a needs to be implemented. -The default "industry entry point" for video and PCI (0xFFE6E) should -also be implemented. (any others?) They should either be routed to -int 0x42(0x6d?) (video) and 0x1A (PCI) or some other interrupts to -trap them. Mapping of system bios might not be a good idea.
