OS/2 checks
for installed
hardware
during startup |
This check may take some time...
(Particularly if you have an older Computer :-)
To turn off this check:
- Open the OS/2 System folder.
- Open System Setup.
- Rightclick on Hardware Manager.
- Select No on hardware detection during startup.
- close the folder...
OS/2 will not check for installed hardware during startup anymore.

Bitmaps in
folders |
It can be fun to add bitmaps to different folders. (Mostly to annoy Windooze users :-)
You do it by rightclicking on the folder and selecting Preferences. In the book you now get you can add bitmaps, change colors and fonts...
NB Remember that this will impair system performance. (Especially on older machines with little memory) |
| Filesystems |
If you don't have DOS on the same partition(or at all) as OS/2 you should consider using the HPFS filesystem instead of FAT.
Here is a few good reasons:
- HPFS is faster.(A lot!)
- HPFS have real support for long filenames(I wonder if Win 95/98 will ever get it :-).
- HPFS is automatically Defragmented so that you don't have to do it. (The Filesystem driver always tries to save files as unfragmented, and if unsuccessful, as as few fragments as possible)
- HPFS is sorted so that directory searches are faster.
- HPFS supports larger partitions. (Larger than FAT. Not certain about FAT32)
- HPFS More efficient use of the disk. (Every allocation unit is 512Bytes, NOT 2K, 4K, 8K or whatever...)

| UNDELETE |
OS/2 has a inbuilt Undelete function. This functions by copying all files that are being deleted on a (partition
that Undelete have been activated for) into a special folder (called Undelete :-)
Unfortunately this makes some operations slower: Delete, Move and Printing!
The solution is to disable Undelete on partition where it's not needed. this is done by editing the Config.sys file
on the machine. I that file there is a line SET DELDIR=x:\delete size;y:\delete size. Here you just remove the section for the
partition you wish to disable Undelete for.
A good advice here is to move the printerspooling to a separate partition. (without undelete)
If you have great faith in yourself, you can go without Undelete at all...
PS: Undelete is NOT activated by default. you must enable it yourself... (Remove REM from the start of the SET DELDIR line) |
| Files |
The Files parameter defaults to 20 in Config.sys. This can be changed to 100. Some programs actually needs it this high.
It don't even use any memory... |
| MaxWait |
The Maxwait parameter is one of the more 'mysthical' parameters in Config.sys... What it does is influence the processcontrol in OS/2.
OS/2 have a prioritybased 'round robin' algorithm to decide witch process(program/task) that is to run next.
If a process is not allocated a slot to run in within a specified period because of
too many higher priority processes before it in the queue, then Maxwait number of seconds later it will get a temporary higher priority.
This will continue as many times as necessary until the process gets to run. thereafter the original priority is restored.
This parameter can usually be set to 1 on a Pentium based machine to get a more responsive system. (Normally a process just needs one or two 'bumps' up to run) |
| Threads |
Threads is the maximum number of concurrent processes that can run on the machine. The default values are 256(OS/2 V3.0) and 1024(OS/2 V4.0)
256 is often too small, and 1024 is 'overkill'. Good vaalues are from 384 to about 512.
Warning: This parameter will reserve resources on the computer, so setting this value too high may actually impair system performance...
OS/2 v4.0 uses approx. 80 processes without any user programs... (or so I belive :-) |
