hi i need satellite A500 board LA-4991P bios
thanks

hi all , this my first post here

long story short my friend give me a dead a500 board with multi faults and without mxm graphics card
after changing EC , CPU core driver , 3.3v 5v power supply , and some work i got the board working again

so i decided to convert from discrete to UMA and start this little project , so far i managed to only reroute LVDS signals , clocks , power to use the gm450 internal graphics

still more work to CRT , HDMI but for now i tested and got stuck and i need a hand to solve this problem

with original A500...
