Depends. There are very few people who wrote drivers for closed source operating systems (like Windows in general) and even less people writing drivers for legacy closed source systems (such as Consumer Windows - 9x/Me). Now you can imagine that these people make a great business from that and try to sell their experience and in the end there are only few persons who would write these drivers and open source them (without some company backing them with money).On Monday 31 May 2004 15:43, Fabrice Bellard wrote:Today, someone sent me a patch to emulate a CLGD54xx VGA card in QEMU (currently ISA only card, but I asked the author to add PCI support). It may be a good solution for Win 9x as I won't have time to work on the planned Sis 6326 emulation in the near future.I am wrong to say that it would be easier to write a pseudo video driver specifically for qemu, who would directly talk to the host part, rather than using a already written windows video driver but with obligation to adapt qemu to this driver ?
Basicly yes. I've done a driver that uses the simple Bochs/QEMU VBE interface using I/O ports, but it's only for Windows NT-based systems and not for Consumer Windows, so there is still gap that must be filled. I think that emulating a real video card AND the simple interface (like Bochs/QEMU VBE or VMware) is the way to go.Is it what Filip Navara has done ?
