■ Development history, v1.0 to v3.01
┌────────────────────────────────────···
│
│ AMOS started as an idea. An idea of being able to salvage data that would
· otherwise be lost. I thought this was a great idea, and contacted IBM for
· some technical doc on HPFS. "The doc for HPFS is classified", I was told.
· I was unable to breach this barrier (Does it have something to do with
Microsoft's rights on HPFS?), so AMOS is all my own work.
Without documentation, it is pretty hard to write a program for accessing and
even writing HPFS-drives. And very easy indeed to trash drives, making them
unreadable, OS/2 unbootable, and the like. Which is why AMOS has been such
a long time underway, and which is also why nobody but my beta-testers saw
AMOS until the v1.0 release.
Having written AMOS v1.x, the next step naturally is to include HPFS drives
in the normal DOS drive lettering scheme using a TSR. This is AMOS v3,
which is still read/only, and will probably remain that way for quite a while.
Supporting the structures necessary for writing HPFS drives is costly in
terms of memory...
To make AMOS, hundreds of hours of work have been used. Most of the time has
been used in a sector-editor, trying to figure out the cryptic ways of HPFS.
Enjoy!
