thank you but can you tell me how you were able to load the bios with phoenix slic mode 1.95, i have been having errors loading the bios file? another question is can i use this sliced bios on another aspire 5773z?
Probably you wrong the biosfile. The right one is Q5WP2107.fd EFI/Insyde bios The mod can be done manually with an Hex editor and YES, with this mod you can flash how many 5773z you want (test it on one before !!)
This didn't help Does "remove battery" mean the normal battery or the cmos-battery located on the mainboard?
"remove battery" means the normal battery. When you power-on the notebook look the usb drive led to check if the notebook try to access it you have to find the right key-combination to start the recovery procedure.
When starting up the notebook, the led flashes for half a second. but thats it, nothing more is happening... are there any more possibilitys than fn+b win+b fn+f win+f fn+esc win+esc to startup the recovery-process?
Try to format the USB drive with filesystem FAT32 and try both bios.wph and 10LIB.wph filenames. Try other key-combination (undocumented) too. In some system an USB floppy drive is needed to bios recovery
Thanks for the feedback. I have corrected RSDT, XSDT and APIC tables name with HEX editor (BIOSCOD01.ROM) additionally.
