you mean that PCI card works?
Yes some PCI cards work. I've made several Assiliant 65550 and 69000 based PCI cards work and some S3 based cards work. There are reports of some ATI cards working but I am still having problems getting my ATI M1 based card to work.
Now I changed to a PCI video card,and bochs had run the vga bios,but still nothing happened!
I have no idea what should I do next.
Are you setting up the shadowing correctly? You have to setup the shadowing in loader.s or bochs and the video bios never make it into ram. The stock ADLO setup won't work on the 440bx.
I've attached my loader.s which sets up the shadowing correctly.
Also the DEBUG_SERIAL option in rombios.c is very useful. You can enable it and all the bochs bios messages will be redirected out the serial port. This way you can see if bochs rombios is even getting called. You have to turn it back off to get text on the VGA screen. But your cards VSYNC should happen regardless. (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.
