I have modified this version of RDISK to make it work with kilobyte (rather than megabyte) accuracy.

The download is here:

I made this change because:
-RDISK has an amazingly small footprint, so wanted to stick with it. The closest competition is the IBM RAMDRIVE.SYS that comes with PC-DOS 7.1, and that's over double the size of RDISK.COM!
-I'm working on a DOS boot disk that needs to extract a 7Z file from and to a ramdrive. The 7Z Extractor needs roughly 2.3MB of RAM, so a ramdrive of 6MB would cause the extraction to fail on a machine with 8MB total RAM, and a ramdrive of 5MB would be too small to hold the contents of the 7Z file!

The bootdisk details:

My RDISK changes are hackish (I don't actually know assembly), and as a result you can't make very large ramdrives with my custom build. Therefore, this doesn't supersede the capabilities of RDISK. To avoid confusion, I called my build RDISK-S (as in Small).

I would love to see this option implemented in the next version of the real RDISK!

Thanks,
Paul

PS- I hope this kind of code sharing and modifying is OK. I'm not sure what the letter of the law is with these releases, but my intentions are good!
