Hello! I've installed an Matrox Illuminator Pro framebuffer. Render is working is OK, using RCPADI. No problem on this. But when I try to set the gamma correction output for the frame buffers 3DS crashes and I'm returned to DOS with this message: Abnormal program termination: Page fault CS:EIP=000Fh:00133715h It looks like a memory conflict, one of those you can spent many hours rebooting again and again. Any suggestion? Thanks! Ps: Next week I'm installing r4 upgrade, now I'm with r3

Ignacio, Setting up the Ill Pro can be a little tricky as it takes up so much real estate in upper memory. This is how I have mine setup as if you have more than 15 Mb RAM you can't load the page frame above 1 mb and the board registers need to be included as well. I've got mine working with Windows, with a SCSI ASPI controller, running 3DS over a network. No small feat. First off you should be using RDPADI not RCPADI. The line reads: RDPADI=C:\3DS4\DRIVERS\RDPILPRO.EXP (I'm assuming you're doing NTSC, but if you're doing PAL it should be more or less the same but with a different *.EXP) Make sure that your Config.sys file that the memory areas the Ill Pro is useing for the page frame and registers are EXCLUDED. I'm using D000 for the page frame and the Board registers are at CC00-CFFF. I have a video board at B800-C7FF and a SCSI controller at C800 so in my case with EMM386 its DEVICE = C:\DOS\EMM386.EXE NOEMS X=B800-DFFF and you need a common line for your Ill Pro driver at the end of your config.sys… [common] DEVICE= C:\PROUTIL\PRODRV.SYS CCIR NTSC Yours maybe be CCIR PAL or SQUARE PAL etc. Once you modified your autoexec and config.sys, REBOOT the system and start the 3DS configuration as outlined below. When you first boot up 3DS after installing this driver a file is created called 3DADI.CFG If you've already tried using RCPADI or RDPADI for 3DS you need to _delete_ this file and go through the configuration process again. A new one will be created. To delete the old one you will find it in your C:\3DS4 directory. You also need to add a line to your 3DS CFIG386 Phar Lap file. To do this type: 3DS CFIG386 -CALLBUFS 1 Under the Render/Display heading change it to RDPADI. The rest should remain as you have it for your SVGA card. Then when you have completed your Vibrant Config it will ask you Now here's the final point. You mentioned trying to adjust Gamma. If you try to adjust gamma so that the boxes line up, what you're going to find is that the boxes will line up at a Gamma Setting of 1.0 which means you won't be getting any gamma correction. You don't want to do this. Jonas should have some files about Gamma if you're interested on researching aspect of 1.0. You therefore need to change your 3DS.SET file to have a setting of 720×486 at .901 aspect if you want it to conform to CCIR specs. You will have to select this before you render if you want the correct aspect ratio. If you need further clarification or have addition questions, please feel

Hey, thanks for your _detailed_ explanation. I think my problem was in the pharlap configuration. I just addded that line -CALLBUFS 1 and no more problems. What's more, the resulting gamma correction was 1.68 with 3DS3, it's a very normal value, looks right. Next monday I'll try with r4. Anyway, I'll look for some "lessons" about gamma correction in the library. (I'm setting up r4, the Ilum Pro, an MGA Imp., and a net, all on time. … I've a lot to learn these days 🙂 Ignacio.

Good deal Ignacio! If you get a chance can you explain how you're using RCPADI, this is not documented with the Ill Pro and it might be a useful way to go. BTW you're value of 1.63 sounds good. I'm very curious to know how you've got your Ill Pro setup. R4 should work the same as R3, so however you have it setup now, just do the same, and of course you'll need to reconfigure Pharlap again. Regards, John

John, I can send to you a complete description of my Il Pro configuration, if you want. Note some parameters must be diffferent (we have PAL color in Spain). But if you want any specific info, jut let me know. Ah, yes I've been using RDPADI, It's been my mistake. Thanks! Ignacio.

Ignacio, >> Ah, yes I've been using RDPADI…. << Well that explains it. No I don't think it will be necessary to send your setup since it is RDPADI. You're setup I'm sure is very similiar albiet for PAL. Nice that this one board does both. Glad to hear all goes well! Regards, John

John, (PMJI) I've got an Ill-Pro (SQUARE/NTSC/4M) that has been one major headache since installation. If you've got the time I'd appreciate some advice. Thanks, HH

Harley, I'll be glad to help if I can. I have a CCIR version with component video out. I've used SVHS, RGB and Component out to a multi-standard monitor. John
