If you have a 512MB graphics card, then you have a graphics card with 512MB
of memory and there will be nothing to set in the BIOS. If you are setting
the graphics memory size in the BIOS, then you don't have a separate
graphics card, but you are using on-board graphics. Perhaps you have both
and could disable the on-board graphics and claw back the system memory you
have assigned to it! Basically, you are confusing different types of
If you install a 512MB graphics card into the AGP or PCIe slot, then you
have a graphics card with 512MB. You can't 'set the graphics memory' in the
BIOS for a PCI-E or AGP graphics card.
If you use the graphics 'built-in' to the motherboard*, then you specify the
amount of main memory which will be set aside for on-board graphics. If you
don't have a huge amount of RAM in your system, then it makes sense for the
BIOS to restrict the amount of memory available to the user for assigning to
the graphics chip.
A third type of graphics card is a hypermemory or turbocache (some name like
that) graphics card. These also plug into the AGP or PCIe slot. They have
some memory on board and use system RAM for the rest. I don't know how you
set the maximum system memory limit for these cards, but it won't be a BIOS
setting on the PC.
*Not all motherboard have on-board graphics.
