run fptw64 -f bios1.rom

[kaiomatico]

Still Error 280: Failed to disable write protection for the BIOS space!

I don't know if it helps, but I guess the mod you successful made on this laptop should be pretty similar (same processor generation, same vendor, same release date, most likely same chipset) https://www.bios-mods.com/forum/Thread-R...val?page=2

pay attention to the post 18 and 9, 10, 11.....I try to realize the BIOS firmware software by

run fptw64 -rewrite -f bios1.rom

fptw64 -rewrite -f bios1.rom also says Error 280...
I've read that in this thread a hardware clip was used for flashing, but I won't do that. I already flashed many PS3's with hardware cliips and I know how tedious it can be sometimes. So that is no option I think.

I hope you can get the BIOS mod to work just with software flashing. Thank you in advance, I'll go get some sleep, hope to hear from you tomorrow

run fptw64 -rewrite -desc -f bios1.rom

Well that looks a little bit better

test and report

[kaiomatico]

After running the above command with the screenshot fptw64 -rewrite -desc -f bios1.rom I still have not a menu in the BIOS to set the DVMT pre-allocated size to 128mb or anything like that. The default value also has not changed, as my graphics driver still reports the old dvmt pre-allocated value.

This first stage
