pflatline Posted February 10, 2006 Share Posted February 10, 2006 Does anyone know a source of intel ,winbond, or sst 8MB firmware hubs. Its part of my devious plot to hack an EFI bios for my 865pe based motherboard. So far I have found a source of Atmel parts,which should work,but Im not sure if I can readily find a flash utility that supports that brand. It seems that there is an intel 865P based board that uses an EFI firmware. The firmware fits in a 8Meg flash part. For those (such as myself) that havent paid attention the last few years, intel added a few extra functions to the flash bios and now calls the part a firmware hub. They are standard parts and many vendors make them. One of my boards has a winbond and one has a SST firmware hub,(both 865pe boards,with 2 and 4 meg hubs respectivly) I suspect the boards will support the 8meg part (I know the chipset does at least). The pinouts are also the same. My plan is to carefully snip the select pin,of the bios and bend it up. Then carefully desolder the stub. Then I will bend up the cs pin on the new chip and solder down the remaining pins to the old chip. Last,I will attack short lengths or wrap wire to a jumper block and wire it up to select which is the active chip. I can then start hacking around with the Intel EFI firmware. With some luck I should be able to rig a hacked efi firmware for my 865PE board.

R. Bear Helms Posted February 13, 2006 Share Posted February 13, 2006 The significance of EFI to the booting of OSx86 has thus far proven to be a non-issue. I have no EFI and I can boot and answer questions on the UNPATCHED 10.4.4 restore DVD. However, the moment it's about to do its language selection thing, where the TPM check comes in, that's where I'm stonewalled. TPM is going to be a VERY dirty word on these boards... I was afraid Apple would encrypt the OS using it, and I now get to pat myself on the back for my amazing visionary prowess... ...and hate that OS technology had to advance so far that you need to encrypt it in distribution. I sure miss the good ol' days when you could hang a logic analyzer off a chip and see exactly what a CPU was doing... nice trace buffer, disassembled code, data readouts... reverse engineer's favorite plaything. Now it's about as useful as Windows 3.0. Link to comment https://www.insanelymac.com/forum/topic/8862-intel-or-sst-8mb-firmware-hubs/#findComment-55915 Share on other sites More sharing options...
