Need help with SPI ROM recovery header
by lasvegaswireman - 8/4/11 7:04 PM
I have a p6130y that has a Pegatron M2N78-LA aka Violet-GL8E motherboard. I made the mistake of accepting a BIOS update via one of HP's update services which BRICKed the computer. I have tried to recover it using various boot block recovery methods but it appears that the boot block is also corrupt.
That said, I have a BlackCat USB JTAG/SPI programmer and notice a SPI ROM recovery header on the motherboard. HP's website states "This connector allows qualified technicians to reload firmware into the SPI boot flash in case there is problem with the data. This jumper should not be changed." I have tried to use the header per HP's pinouts but the programmer can't find the SPI ROM chip.
Anyone with information about the use or function of this header, please respond. I would like to know if it follows standard SPI specs or if it is a modified proprietary HP version. Do I need any buffering or isolation circuitry, etc. Any useful information that aids me in recovering this machine would be appreciated.
