You'd be correct in that attempting to get the persistent RamDisk would be very difficult. However, the non-persistent RamDisk can be set up pretty easily. The problem is that it uses the same 32 MB that the rest of the operating system, Today DLLs, SIP DLLs, etc. use, so it's difficult to have a RamDisk of any appreciable size if you have other things running. I was trying to have the RamDisk allocate memory outside of that 32 MB by attempting to use VirtualAlloc() instead of LocalAlloc(), but I probably missed something, since when I tried it out, it didn't work for me... :(

If anybody around here knows more about Windows Mobile programming than I do, I'd be happy to try and help get it to work (I'm more of a Unix programmer than a Windows programmer!), since I'd love to have all of my caching on a RamDisk than this slow flash memory stuff. :wink:

Thanks, gents - that's awesome information.

Now, if I could push my luck - what are the tradeoffs in paging pool sizing - same as for the RAM Disk, or is this a different issue?

Thanks!
