i am trying to downgrade a Sony Vaio VGN BX51VN, but i get stuck right at the begin of a clean XP installation because of the APCI thing. the system has been blocked .... check an update version of the BIOS and there is the following error
while doing the installation instead of F6 i pressed F5 and chose STANDARD PC from the list
stop : 0x0000007B (0xF78DA63C, 0xC0000034, 0x00000000, 0x00000000)
Could you please help?
