I have upgraded the GVP ROM to the latest of 4.15. I have two of them and 4.0 and 4.4 would not boot. It wasn't until I burned the 4.15 EProm that I got it to work on the A4000. I get around 1M/s SCSI2 according to SysInfo. I want to get the SCSI2SD V6 card. I have them in my other A4000s. The GVP Impact 2000 HC8 Series II has 8MB of RAM it says as 24bit. It is definitely Z2 because I was testing an A2091 with 2Meg RAM and it wouldnt see it until I configured the GVP to 6MB.
How this Amiga came about was I bought a "dead" A4000 MB on ebay. I figured I could fix my original A4000 from the capacitors leaking and killing the audio. Come to find out, somebody put Buster in wrong. I don't know how they forced it in there but they did. I put it in correctly and it booted up. I then bought a new Buster chip and it ran fine. I then recapped my other A4000s and switched MBs around all in good working order. Even the clock battery works. So I had this A4000 MB with no home. I saw a daughter card is so expensive and good luck finding a case to fit it so I went with the new Mediator III card. I would get to experiment with PCI cards, NICs, USB, etc that Elbox drivers are written for.
I didn't know you could allocate Radeon memory for the Amiga. I tried to install my CV64 but it appears to be dead. You can read my other post asking for help troubleshooting it. I tried it in my Amiga with CyberVisionPPC and showCGXconfig sees "0 devices" but the boot screen and showconfig sees the Phase5 CV64 with 64meg of memory.
I have installed OS3.9 up to BB2 a couple times now troubleshooting the CV64. So I am just waiting on my PS cable. Good advise there on the ATX PS. When I was troubleshooting the CV64, I noticed 5V does a lot in the machine. On the CV64, 12V and -12V are only for the video switching chips from passthru to CV64 video out.
