RE:     Executing FatOpt and FatSort in memory constrained environments.
 
FatOpt and FatSort may encounter problems when executed in memory 
constrained environments such as when executed from a OS/2 boot using 
floppy disks. In this environment, swapping is disabled by default and 
these utilities may exhaust memory and fail. In some cases the failure 
will be associated with a message that there is insufficient memory. In 
other cases the program may fail with a trap message.
 
In these situations, the customer should prepare boot diskettes in 
accordance with the procedure shown below. This procedure is tailored to 
Warp V3. The customer may modify it appropriately for OS/2 2.1 as well.
 
1. Create the Warp Utility disks by opening the System Folder, then open 
   the System Setup folder, then click on the Create Utility Diskettes 
   icon. Follow the instructions provided. This procedure will create 
   three (3) diskettes which should be labeled accordingly.
 
2. Copy the FatOpt.Exe and FatSort.Exe files to the Utility Disk 3.
 
To execute the utility, shutdown the system and boot from Utility Disk 1. 
When you receive the A> prompt, insert Utility Disk 3 and run the utility 
as you would normally.
 
If memory related problems still exist and if you have another hard disk
volume other than the volume which you wish to optimize or sort, the 
following procedure may be used to circumvent the memory problems. If no 
other drive exists, you will be unable to execute these utilities on your 
current hardware configuration.
 
1. Insert Utility Disk 2. This diskette contains the Config.Sys file for 
   the floppy boot process.
 
2. From and A> prompt, copy the config.sys file using the following 
   command:

       COPY  CONFIG.SYS  CONFIG.OLD
 
3. Edit the Config.Sys file on Utility Disk 2 and make the following 
   changes:
 
    Change the line which reads: memman=noswap to memman=swap
 
    Insert a new line after the memman line which reads: 

       swappath=d:\ 2048 2048

    where d: is a hard disk volume other than the one to be optimized or 
    sorted. This volume should have several megabytes of freespace.
 
4. Boot again from the Utility Disk 1 and attempt to execute the FatOpt or 
   FatSort utility.
 
This procedure enables swap processing while booted from floppy. It will 
use the disk volume specified for the swap file. Once you boot from hard 
disk, you will find a Swapper.Dat file in the root of the drive you 
specified in the swappath statement. You may delete it if you desire as 
it will no longer be in use.
