I tested it today at my university and it did work :)
Now, where can I get a free version that can handle this much RAM?
It is a bit illegal to use himem.sys from MS-DOS 7.x on a computer that
doesn't have a license for it - although it is IMO a bug-fix. And I was
thinking of approaching the guy in charge for that room with some ideas for
changes. For instance a bigger disk cache then the default, new mouse
driver (cute mouse instead of the current that uses 24K) etc.

I do not think there whould be any such problems. I didn't test it much at
school (Pentium Pro 200 machine) but it seemed to work fine. Of course I'll
be using it more in the future since it's the fastest way to get connected
to the InterNet (via Arachne).

Weren't there any more diffrences? IIRC OSR2 is a little more stable. (And
2.5 much less stable - I haven't tried the other Windows 95 versions).

I can always tell a lie ;)

I'm wondering what use 64MB of Disk Cache (as soon as I find a program that
has a higher limit then 32MB) would do when the FAT16 drive is only ca 150MB ;)
