Re: VGA Problem about 440bx chipset
Wow! I got it! I use another S3 video card,and succeeded in bringing up the VGA,and Excellent. Its really touchy about what VBIOS will work and what won't. I haven't been able to narrow it down as to what the missing piece is yet. ATI seems to be the worst though. Probally because of all the bios extensions they use. perhaps it would make sense to summarize lessons learned and send them to list, so that whoever will play with ADLO next can benefit from the knowledge Setting up a known to work table of chipsets vs cards may be a good idea as well. Just put in all right keywords so that it is easie to find it later on, like ADLO, S3, etc. The shadow patch probably isn't big either. After my initial post of the patch (about a 1.5 years ago) I never really tried to push the patch upstream since its chipset specific. What's really needed here is vga expansion rom shadowing support in the pci resource allocation code. So that you could do something like this in the config file. option SHADOW_VGA_BIOS=1 option SHADOW_VGA_BIOS_DEST=0xC Then the mainboard chipset code could handle copying it from the PCI ROM to the shadow location and ADLO would not need to know anything about how to shadow for a specific chipset. I for one could really use this feature. I'd offer to code up an implementation for the 440bx but I don't have much of a clue on how the PCI resource allocation works. ___ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios

ron minnich wrote: option SHADOW_VGA_BIOS=1 option SHADOW_VGA_BIOS_DEST=0xC we'll put this on the list, though not quite this way (unless you want it in V1) Well until myself or some other industrious soul ports the 440bx stuff to V2 its not much use to me unless its V1. It dosen't really matter to me how its implemented in V1. If you have what you think is the right way then I'm game. And if someone will guide me through what needs to be done in the PCI allocation stuff I'll give it a whirl but at first blush that PCI allocation stuff appears fairly complex. I guess the part I need help on would be the methodology of the ROM expansion address assignment. The actual copy seems pretty trivial. - Scan for the id of the vga device. - Get the rom address and enable the decode. - set the shadowing. - do the copy. - disable writes to the shadow. - disable the ROM decode.

(assuming the vbios runs correctly) I leave in a few hours and won't be back till Tuesday the 2nd so you are on your own for a few days. I'll try to check email during that time but I'm not promising anything. Search the mailing list for things like ADLO, vgabios, etc there are several threads on getting this up. ;* ; $Id: loader.s,v 1.1 2002/11/25 02:07:53 rminnich Exp $ ;* USE32 ; code it is loaded into memory at 0x7C00 ;* nop nop ;* ; A) setup GDT, so that we do not depend on program ; that loaded us for GDT. ; Ex: LinuxBIOS and EtherBOOT use different GDT's. ;- ; 0) cli ;- ; I) lgdt [0x7C00+protected_gdt] ;- ; II) setup CS jmp 0x08:0x7C00+newpgdt newpgdt: nop ;- ; III) setup all other segments mov ax, #0x10 mov ss, ax mov ds, ax mov es, ax mov fs, ax mov gs, ax ;- ; IV) ; not now ;sti ;* nop nop ; Outputs a value to PCI config space ; put the bus,dev,function,offset in eax ; and the byte value in dl then call this macro MACRO PCI_CONFIG_WRITE_BYTE shl edx, #8 mov dl, al and dl, #3 shl edx, #16 or eax, #0x8000 and eax, #0xfffc mov dx, #0x0cf8 out dx, eax shr edx, #16 mov al, dh mov dh, #0 add edx, #0x0cfc out dx, al MEND ;* ; B) shadow - ON (enable/read/write) ; This is orginal shadowing setup code ; Works on the Matsonic 7308e mainboard ;mov eax, #0x8070 ;mov dx, #0x0cf8 ;out dx, eax ;mov eax, #0x ;mov dx, #0x0cfc ;out dx, eax ; This enables shadowing for the 0x0f - ; 0x0f range and the 0x0C - 0x0c range ; for the 440bx chipset. mov eax, #0x59 mov edx, #0x20 PCI_CONFIG_WRITE_BYTE mov eax, #0x5A mov edx, #0x22 PCI_CONFIG_WRITE_BYTE mov eax, #0x5b mov edx, #0x22 PCI_CONFIG_WRITE_BYTE ;* nop nop ;* ; C) copy -- boch bios ; counter - 64kb. mov ecx, #0x1 ; source - 0x8000 ( 0x7C00+0x400 = 0x8000 ) mov ax, #0x10; src-segment - 2nd entry in GDT mov ds, ax mov eax, #0x8000 ; src-offset - 0x8000 mov esi, eax ; destination - 0xF mov ax, #0x10; dst-segment - 2nd entry in GDT mov es, ax mov eax, #0xF ; dst-offset - 0xF mov edi, eax ; clear direction flag cld ; the copy rep movsb ;* nop nop ;* ; D) copy -- video bios ; on my system video bios is just 48KB (0x0C000) ; but just for paranoida we copy 64kb (0X1) ; counter - 64kb mov ecx, #0x1 ; source - 0x18000 ( 0x8000+0x1 = 0x18000 ) mov ax, #0x10 ; src-segment - 2nd entry in GDT mov ds, ax mov eax, #0x18000 ; src-offset - 0x18000 mov esi, eax ; destination - 0xC mov ax, #0x10 ; dst-segment - 2nd entry in GDT mov es, ax mov eax, #0xC ; dst-offset - 0xC mov edi, eax ; clear direction flag cld ; the copy rep movsb ;* nop nop ;* ; E) copy -- pirq table ; on my system video bios is just 48KB (0x0C000) ; but just for paranoida we copy 64kb (0X1) ; counter - 256kb -- 0x100 mov ecx, #0x100 ; source - 0x7F00 ( 0x7C00+0x300 = 0x7F00 ) mov ax, #0x10; src-segment - 2nd entry in GDT mov ds, ax mov eax, #0x7F00 ; src-offset - 0x7F00 mov esi, eax ; destination -
VGA Problem about 440bx chipset
HI,all I run linuxbios on a 440bx chipset mainboard using adlo+bochs,I can boot linux but still havn't started up the vga. what should I do if I want to bring up the vga card? I found the work done about vga are: (1) allocate_vga_resource() in newpci.c enbale io/mem of the vga adapter then walk up the bridges setting the VGA enable (2) copy the vga bios to 0xc using adlo,and run bochs bios. I'm not sure if it had initilized the vga controller enough. And I found there are some registers about AGP from 440bx northbridge datasheet ( 82443bx hostbridge/controller),such as AGP capability identifier register,AGP command register,AGP status register... But this work hadn't been done in linuxbios,maybe I need to set these registers correctly according to the datasheet to enable AGP?

None of the AGP stuff is setup in the 440bx code. Only PCI cards have been used to date. You will have to write AGP init code. Does V2 know anything about agp? If so then its probally time to port the 440bx stuff over to v2 ___ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios

It does know in some ways. ron ___ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
