Sure, you can dump it and post it in the "New Dumps" thread.
It will probably come in handy at some point, when VL and PCI is in a more usable state ...

DirectX 8.0a Direct 3D Software Rendering Test:



Yes, it's doubled, but very impressive nonetheless smile Slight graphics corruption appears afterwards.

Hardware Acceleration was set to the second option, which is "Basic". The third option (or second last if you prefer) causes the mouse only to be displayed and the desktop black with a few weird coloured lines scattered about.

Daytona USA PC Demo For Windows 9x (C) 1996 Sega: Again, the screen is doubled like the one above, but I've cropped the image this time. The game runs at 1 frame about every 3 seconds. Awesome!

Added memory-mapped I/O to the S3, as Windows 3.1 makes heavy use of this feature.

Made co-ordinates always relative to the start of VRAM. Fixes Virtual Pool (with S3 accelerated drivers enabled).

Took a while but it works.

It was hard to find any consistent info on how the page register and the top most bit of the 16-bit dma interact. The 5170 schematic shows that the lsb of the page register is masked and the msb of the dma controller is passed to A16 and that seems to work. Dosbox appears to add them while Bochs appears to or them.

Agree with the above post great progress.

I do have a question about the memory configuration for the 386 and 486 driver the -ramsize switch is limited to:

1664K,2M,4M,8M,16M,32M,64M

as far a i recall a 486 could only logically use 15MB. If i try setting MESS with -ramsize 16M the bios only sees 1664K i don't know if that's a bug or not?

Also AFAIK 12M should be a valid setting.

Just for amusement i changed MESS to accept 15M and it seemed to work.

I've encountered a problem trying to install the sound blaster 16 drivers 'sbbasic.exe' in the at486 driver.

I can't gain access to the local hard drive C:



I'm using the latest SVN 17630 (x64 Windows 7).
