Max TOLUD
Dynamic
Maximum Value of TOLUD. Dynamic assignment would adjust
TOLUD automatically based on largest MMIO length of installed
graphic controller
NOTE
:
If there is a problem with an external graphic card or
with other combined PCIe devices and its drivers, the problem can
be fixed by changing the max TOLUD value 3.5GB instead of
dynamic.
The dynamic value is the intel recommendation for 64bit OS’s, but
does not work for 32bit OS’s.
By selecting 3.5GB the BIOS will automatically reduce the TOLUD
value to the optimum value according to the PCIe space required.
You should then see in Windows what memory is available
