[comp.os.minix] Some questions...

I have some questions about Minix (ST-version, if that makes any
difference)...

1) Why can't mined (nor mg for that matter...) handle large files?
50K is too much, don't know what is the exact limit. It shouldn't
be a memory problem, I have a 1M machine and a 360K root file-system.

2) What is the real meaning of (not life, but..) chmem? I know what it 
does, but I'd like to know if the memory+stack allocated by the cc is 
normally enough? That's because quite many posted programs seem to have 
a notice saying that I should chmem the program to some determined value.

I had something else in mind too, but I can't recall it now. Anyway,
I'd appreciate any answers for those two...

It is for computers that don't have memory management hardware. The
full amount of memory required to run a program has to be allocated
in advance (in a practical implementation), and chmem is used to limit
it.

>1) Why can't mined (nor mg for that matter...) handle large files?

Don't you get more by allocating more with chmem?
