Error flashing Mac V5 to PC V5

[cccdddrrr]

I downloaded this package -

Then I put a Mac Voodoo5500 PCI card in to my Intel 440BX mobo, and booted up (using a Radeon AGP graphics card) to get to the "safe command prompt".

I ran this -

flash v5dvipic.rom

But then I see this -

There is no build information for the selected hardware. Continue (y/n)?

So I type "y", but then I see this -

ERROR: Unknown flash EEPROM manufacturer (Man. ID: EEh, Dev. ID: FFh)

If I run PCI.exe (a useful utility to see what is sitting in your PCI slots), it finds the card, but thinks that "Bus Access" is disabled - whatever that means.  It also thinks that the card's "subsystem" is a Voodoo5 *AGP* 5500/6000.  Eh? AGP?

Any thoughts on this matter would be very gratefully received.

Thanks a lot, from Robert.

Solved. I tried flashing the card on a different machine - a Pentium IV PC, and it flashed OK.

Although it worked, I get a strange side effect - if I choose a screen resolution of say 800x600, that's exactly what I get on the screen! In other words, the LCD screen's DVI image is 800x600, with a very large area of "nothing" all around the outside. Everything looks like this - the desktop, games, etc. Sure, if I crank up the desktop resolution to 1280x1024 (my monitor's native resolution), the entire monitor's screen is covered with the desktop image. But many of my games don't run in that resolution, and also, I am happy to play some games in lower resolutions such as 800x600.

Perhaps this resolution problem mentioned above is a driver problem? (I'm hoping it's not a "V5 Mac to PC" BIOS problem.) It may be a cable and/or monitor problem?

I think this is a monitor setting-try looking for something like "stretch lower resolutions on/off" in the OSD menu.

Yeah thats odd..a Voodoo 5 scales on my LCD at lower resolutions (although its running through VGA, not DVI). Its got to be a registry setting or something, because my monitor has no such setting in the OSD and you can control it in a graphics cards setting page usually..But personally, LCDs look terrible outside their native resolutions.

The "Mac to PC" V5 displays OK if I use the VGA output.  This strange "non-scaling" behaviour only occurs if I try and use its DVI output.  Also, my LCD has no hardware options to adjust scaling.  I think I might need a software scaler, like RivaTuner, but I'm not sure what the utility is called.
