first of all, sorry for my english.
I'm struggled with upgrading VGA (G750JW + 780M).
I already bought all of parts and assembled it.( vga, heatsink, fan, bottom case, 230W brick. etc.)
but, without modded bios, windows recognized my VGA as 'Microsoft basic display adapter', not 780m .
so, I'm trying to change vga id 765m to 780m by modding bios.
but it's really really hard for me, even flashing bios, (always showing 'ROM file size does not matching~~~')
now, i got 2 problem
1, in bios rom by using mmtool, which volume(or index, or file name, what ever) has vga(vendor+device) ID strings that i should change?(or what tool do i need)
2, any suggestion about flashing bios?
please give some advice and help.
