Does anybody  have an idea of how long does it take to transfer a 2 MByte
bitmap from system RAM to a VGA video controller video RAM when that
controller is plugged into a PCI / PMC slot on the mainboard ?
I am using an Pentium 233MHz PC with SRAM with a VGA card with GD5480 cirrus
video controller.
Is there any valid reason to think that transferring 2 MB in the opposite
direction ( from VGA RAM to system RAM ) could take longer ?

Thanks in advance
