I'm a computer tech, but I don't work on HPs much. So my grandma's motherboard died on her HP a6750f desktop computer which has a MS-7548 motherboard. When I replaced the motherboard with one I ebayed (which was supposed to be a new motherboard), the new computer wouldn't boot. I figured out that I think the the 5.11 bios won't work with the x4 9650 that was originally in it. I stick an older AMD processor in and it boots great. Slow, but works. So I tried the bios update from HP but it fails with a "Your system does not meet the minimum requirements for this update. Update has been cancelled. (9996)." I also notice that my Vista needs to activate. After digging, it's my guess that the the new bios needs to be tatooed. So I find the only version of iso dmi tool I can find that's still available and I run it. It seems to think it works, but doesn't help me at all. My DMI info according to the tool: Vendor: Hewlett-Packard Product: PPPPPPP-CCC#MMMMMMMM Version: Serial: (I never checked the above until after I tried to run the tool once so I'm not really sure what it was originally) I don't think I care about the DMI as long as I can activate vista with the key on the computer. Do I really need the DMI to run vista? Am I going to have to reinstall vista to activate or can I just activate and continue along now? But I still then have the problem of how to flash the 5.13 bios. I unpacked the bios update executable and have the 5.13 bios file. I read somewhere about people using a newer version of winflash to update in windows 7. Would a newer version of winflash help me? Any hints on where to find it if so? I tried running winflash in a commandline in vista (the version that was packed with the bios) and it didn't do anything. Tried with a /? and with the bios filename and it still didn't do anything. I'm afraid I have to do it from a boot disk but I haven't used a floppy drive in years (nor do I have one). The computer has no option to boot to USB. Any guidance would be appreciated!
