i have a 4mbit flash eprom
flashend with my pc with xecuter2 bios
than i soldered the two points to the flashrom from the first picture of this page
someone told me that i dont have to solder the points from pic 2,3 because this are only usefull for the onboard eprom
(please say if he´s wrong)
ok now i can flash but its stopping at the half of the flash progress
and the bios cannot start anymore!
i have no switch anymore!
the complete chip should be writeable!
i only wanna have the vga bios on my chip
my chip: AMD - Am29F040B

8mbit == 4x 256KB, 2x 512KB, 1x 1MB
4mbit == 2x 256KB, 1x 512KB
2mbit == 1x 256KB
the xbox TSOP is 1MB
dont mistake 4Mbit for 4MByte... completely different things
you have a 4Mbit chip.. u need to flash it with a 512KB bios file... u can make it with some programs or in dos (i forget the exact command line)
copy biosname.bin + biosname.bin finalbios.bin
that takes a copy of biosname.bin and doubles itself to make it 512KB
if u use 2 diferent bios's the second bios will boot by default.. u can add a switch later..

the evox.ini is right! the bios is 512kb(VGA BIOS NOT 2 BIOS IN ONE)
when im flashing a 256kb image the flashing will end with success
but when i wanna flash a 512kb image the flashing will stop at 50%
i dont have a switch installen!
