<H2>Comparison List for Vidspeed v4.0</h2>
<hr>

Thanks for your contributions! The UNIVBE difference for S3 cards
is very interesting. Was this a relatively recent version of UNIVBE?
(I talked to the UNIVBE author a few months ago, and he was just
discovering how to do SVGA modes better than the BIOS, programming
the S3 chip for a limited "linear-addressing" mode).<p>


The PVI486-SP3 seems to have relatively poor PCI performance (confirmed
by different sources). I would be suprised if the SiS PCI chipset used
didn't have decent CPU-to-PCI buffers, apparently the BIOS always
leaves it disables because of some problem. I've got an AP4 (Intel Aries)
myself, which has decent PCI performance (Stingray Pro PCI DX4/100),
but cannot do reliable zero-wait cache timing, I was thinking of
swapping for an SP3.<p> 

Here's the current list.<p>

(1) Burst-mode disabled?
(2) UNIVBE TSR not loaded.
(3) UNIVBE TSR loaded. Makes HUGE difference for SVGA modes on S3
    chipsets.
(4) On Asus PVI486-SP3 motherboard (SiS chipset). Apparently current
    revisions of this motherboard have very poor PCI performance.
