#ADPro Memory Help

I recently purchased ADPro 2.3. I attempted to load a large IFF file and got an error message saying there was insufficient memory to load it. I have 12 Mb of RAM, composed of 4 megs of 16 bit memory in a hard card, and 8 megs of 32 bit memory in a Progressive 040 accelerator. The ADPro "ABOUT" function says I only have a bit over 4 megs for the buffer, and the image required something like 4.1 megs. The only thing I can find in the book is some reference to "contiguous" memory, and I'm wondering if for some reason ADPro is not recognizing my 8 megs of 32 bit memory. Is there some way to get it to recognize the entire 12 megs. Thanks.

Consult the manual section describing the MAXMEM tool type. By default the MAXMEM tooltype is set fairly low.

Thanks for the response on my memory problem. I tried upping the MAXMEM limit, and even removed the limit altogether. However, it didn't change anything. It seems everything else recognizes my 12Mb except ADPro. Any ideas ? Thanks.

Could you please redescribe your hardware layout? IE: what memory is located where.

#69077From: Jim MccabeNov 24, 1993 12:34 PM

My memory configuration is 1Mb of chip ram, 4Mb of 16 bit ram on a IVS Grand Slam hard card, and 8 Mb of 32 bit ram on a Progressive 040 accelerator card. I'll try your suggestion of starting ADPro from the CLI tonight. Thanks.

With the memory organization you specified, I think that 8MB will be the most that ADPro can grab. There's no way to put 4 MB of 16 bit memory next to 32 bit memory in the Amiga's hardware map, if memory serves.

Thanks. I tried running ADPro from the CLI as you suggested, and I still couldn't get more than 4Mb for the buffer. Now when you say that 8Mb will be the most that ADPro can grab with my configuration, how would I get the additional 4Mb ?

I don't know, at this point, you are not getting the 8 meg section. Do you have a program which lists memory chunks – one such program is called frags. From what you've told me so far, you should be getting at least close to an 8MB slice. Are you running any utilities or hacks at start up?

I run 8 meg 16-bit on Supra Ram board, and 8 meg 32-bit on PPS 040 and I've never able to access more than an 8 meg chunk with ADPro. Gigamem works just fine with ADPro for large file conversions. ….John

Thanks, John. BTW, what is Gigamem ?

#69186From: Brian BartlettNov 25, 1993 10:28 PM

Jim, Gigamem is a commercial package that adds virtual memory capabilities to programs that are "Gigamem aware". AdPro is one such program. There are others out there, but since I rarely do serious image work, I haven't bothered to track it down. I'm also not sure if there are specific hardware requirements for using Gigamem. If you aren't familiar with the term, virtual memory refers to the capability of using space on your harddrive as additional memory. To make it work, when a memory block is not in memory, a "fault" occurs and the required memory block is swapped in from the harddrive. It's a slower than real memory, but on a fast machine with a harddrive, it may not be noticeable. As with any system sleight-of-hand, it's a tradeoff. More memory for a hit in speed.

Jim, look for a program called MergeMem. You'll probably find it on older versions of the AmigaDOS system. Funny, but it shouldn't be a problem with the current version of AmigaDOS (2.1) as it seems to merge all existing memory automagically. Brian bjbart@watnxt01.ucr.edu

#68954From: Jim MccabeNov 22, 1993 10:05 PM

Thanks Brian. I tried a version of MergeMem called JoinMM (I couldn't find MergeMem on my 1.3 disks), but it said I've already got 12Mb, and it couldn't do any merging. I think you were right that AmigaDOS 2.1 already merges it; however, ADPro doesn't recognize it for some reason, although everything else does. Any ideas ?

From a freshly booted system, please try running ADPro from the CLI and then hit the HELP key on the keyboard. The primary image buffer size should be given in the resulting panel. Running from the CLI (as in simply: ADPro:ADPro will cause ADPro to consume as much memory as it can. See if this gets you a primary image buffer larger than you've had before.

#69163From: Brian BartlettNov 25, 1993 1:59 PM

nope. If it's not a problem with the maxmem and it's contiguous, then it _should_ work. Brian bjbart@watserv.ucr.edu
