@TTAV134 and Serg008 I've read both your postings first about flashing a BIOS eeprom chip with the Willem programmer, while the chip itself is detached from the mobo, second the actual "modified" HPQFlash .CAB- file by Serg008. I, as you've already have noticed, own a HP Compaq 6710b notebook, flashed with that non-modifyable F.20 version software. So your experiments brought me to the same conclusion, flash the chip in a programmer. I'll have to think what kind of programmer i should buy, a whole system (pcb-board) or an in-circuit thingy but i'll guess that's not so important for now. Please, i have some questions for (both?) of you, TTAV134 your PM is full and exceeds it's limits i've just read... So here it goes. If i read the whole eeprom in a programmer and save the output, the binary to disk, where do i put the SLIC v2.1 markers (i've noticed that my eeprom needs them twice), i.e. what is the offset? Are both SLIC v2.1 tables attached to each other, i.e. do the follow one-another or are the spread on different offsets in the BIOS binary? ...and then, i'am not that good with software, more a hardware guy (electronics), where do i get these HP SLIC v2.1 softwares? I still don't understand how this works. I've tried to read as much postings as humanly possible (square eyes), but i'am still baffled on the subject... Ok, hope to hear from you, i'am very anxious to know your comments. Serg008 made me a "modified" .CAB file for my notebook (very, very appriciated!), but this is a 1MB file, and i did see in the datasheets that all eeproms are 8MB or higher, so i'am missing something here, i'll guess... I can't program this modified file directly into the eeprom. Anyways thank you for your attention and time. B.T.W. Does anyone know how to open (un-screw) a 6710b notebook? ...and what the partnumber is of the BIOS eeprom chip of this notebook? Also a 25x32vsig or another type?
