Maybe it icr2 doesn't like too much RAM?

Is there any way to set an upper limit?

i think original ms-dos 6.2 only sees 64MB
at least that is what i see when i type
mem/c/p

OK, so it's not the amount of ram. Ms-dos call not implemented by freedos. But you're running pure ms-dos, not freedos.

DOS4GW games may have issues with too much RAM in some cases, just try to use himemx.exe that can limit amount of XMS - set e.g. 256MB limit, DOS4GW will be then limited too...

Thanks dude! Will try that.

Same error. Maybe having too much physical memory prevents the VRAM from being mapped into a specific address range. The machine has 12 GB of RAM (don't ask why I don't have 16 gigs here).

Hi Rendition Users,

I own a GENOA V-Raptor 3D PCI card and can not find the latest BIOS to download which prevents me from using the drivers (black screen error).
Perhaps someone has the package saved on HDD or so, my BIOS is only 1.00.

I am looking for the package

gen-148.zip

listed here on web.archive.org: http://web.archive.org/web/19980615081908/htt … _drivers1a.html

Via Google I only found dead ends to a stupid update software: https://www.video-drivers.com/drivers/5/5676.htm

I also got a bug in playing the Verite Version of Descent 2 with the card: The screen is tinted more red as normal in the game, tested under DOS and Win98SE.

Thanks for reading.

Descent 2 its common bug on v2100 and v2200 rendition cards, only earlier v1000 cards rendering game perfectly.

I don't know how modern PCs behave with too much RAM, maybe look for some remapping option in SETUP. On my old SandyBridge system with 8GB it splits the memory map this way:
0-cca 3,5GB - user RAM
3,5-4GB - MMIO, BIOS
4-8,5GB - "extended" user RAM
so I have all PCI devices mapped below 4GB boundary and no problem with acess from legacy OSes. But I didn't tried Verite card on this machine yet.
There are some DOS tools (I think Japhet's jemmex/himemsx package contains some cmdline tool too) that can display physical memory map (some BIOS INT service should report it too)...

Thanks, will check it out. I really need to get icr2 running.

both dma and nodma, both cart racing and nascar 2 work with 256Mb memory and don't work with 512MB memory (n2rend.bat sometimes works with more memory)

Did you pull sticks out or cap it with himemx?

sticks

Hm, strange, did change the base address of LFB/MMIO? (e.g. can be read from PCI BAR) between 256M and 512M of physical memory? I don't see a reason why higher address (if changed) shouldn't work. Maybe some stupid chipset limitation that can do DMA only for specific physical low memory range? Something like some chipset doesn't cache higher part of RAM?

On my crappy mobo, I can't remap anything. My sticks are 4gb each so I can't go any lower than 4 gigs. I don't think I have a pci hole option either.

I think the problem with ICR2 is, it remaps the 16 Mb of Rendition physical address space to a low logical address. My speedy3d test app, which still doesn't work, has no problem mapping rendition physical address 0xeb000000 to logical address 0xeb000000 (numerically identical).

after starting rebel moon or vquake: cart racing and nascar 2 no longer work.

It probably doesn't uninitialized the board on exit properly.

sorry, no idea why 512mb wasn't working before but it works (i guess i tried rebel moon before to test whether it works at all, cart racing didn't work after that, so i moved on to testing next memory stick)
cart racing and nascar 2 work with 512MB ram
this is how it is:
sdr, athlon works
ddr1, athlonxp works
ddr2 (1GB), phenom doesn't work
ddr3, i5 doesn't work

So 1gb+ is too much.

I take it the i5 has 2 GB+ RAM?
