Zeroth, english is not my first language.
First, I'd like to warn you I don't read this newsgroup. So please forgive
me if I am breaking any implicit rules particular to this newsgroup.
If you know what headroom is, skip this paragraph entirely.
I don't know how common that program is, so I include a description.
Headroom is a "memory manager" in that it allows you to move
your TSRs past the 640K barrier and assign them a new hot-key.
How it works, is that you first load the headroom TSR, then load the
rest of your TSRs, and finally, you swap them out into the high memory,
using the swapout program provided with headroom. From the headroom TSR,
you can assign hot-keys and create a configuration file (a batch file)
that will recreate the environment (TSR and hot keys) if executed from
your autoexec.bat.
A friend his having trouble saving his headroom configuration file.
When he tries to, he gets "Unknow error reading drive C:"
(Drive C: is an 85 megs Seagate, all in one big partition.)
and the traditionnal "abort, ignore, retry". What is less traditionnal, is
that none of the options work!!! The only thing you can do is hit the
3 nameless keys to reboot.
I have lost touch with the IBM world for the past year and I don't
know much about DOS4.01, so I haven't been able to figure out what
is wrong. My theory (an uneducated one, but it's all I have to offer)
is that headroom 2.0 still sticks to the 30 some odd megs limit of DOS3.3.
But I have not seen any mention of this in the manual.
To be precise, his hardware configuration is:
AT 386
2 Mb extended RAM (that is 2 Mb of total memory)
DOS 4.01
HD Seagate ST296N -- 85 Mb -- 20ns
How to produce the error:
C:> headroom
C:> sidekick (or any other TSR)
C:> swapout (from the headroom 2.0 distribution disk)
C:> atl-<CR> (headroom's hot-key)
F4 (secondary menu)
select "save configuration file"
That last command is supposed to create a batch-file that will load and
swapout sidekick, but instead, it chooses to crash the machine.
As I mentionned at the beginning, I will not see any repies posted to
this group (try instead comp.sys.amiga ;-). Please send all replies
via email. I will forward replies on request. If the requests get
overwhelming, I'll post a summary (Yeah, right, like I'm gonna get
50 request for that ;-).
Sincerely, happy hacking!
