I don't know, since I cannot try. I always advise to use the manufacturers DOS related tools.... I don't prefer to flash from XP / Vista. Most bricked boards came from XP / Vista flashtools.... The FLASH895 ma79xds5.f6 command is confirmed to work, the other ways not (yet).....why don't you create a bootable DOS USB stick using HP USB Disk Storage Format Tool? Q-flash could be a useful alternative, but NOT @BIOS... Btw: Did another mod as well. SLP1 and SLP2.0.........
DID you try with the unmodified bios. You should try the new bios unmodified before requesting a mod. Give a bit of a control
