The procedure has changed from the Beta Versions. The Installation disk has SYSINSTX.COM on it as well as OS2KRNLI, OS2LDR, OS2LDR.MSG and a lot of other files which are not needed. Copy SYSINSTX.COM to your C: drive and from there give the command "SYSINSTX A:", where you have a formatted hi density disk in A:. All SYSINSTX does is copy the hidden file OS2BOOT to the A: drive. The other three OS2*.* files on the installation disk are not hidden and you can copy them to a: via C: or by whatever means you want. It is important to rename OS2KRNLI to OS2KRNL on the boot disk being created.

The rest of the required files are all on Disk 1 of the Installation Set and they are listed below. There are a number of files with the numeral 1 in their names. These files are for a CLONE. If you have a PS-2 machine there is a corresponding set, also on Disk 1 which have a 2 in place of the 1. Use those. If you have a PS-2 you probably also need to copy the file ABIOS.SYS which is on Disk 1 also. On Disk 1 there is a file named OS2SCSI.DMD which is not listed below. That is presumably their generic driver for SCSI drives and is probably needed for those with that kind of hard drive, and for which there should be a corresponding statement in config.sys.

I am not sure that all of these are absolutely required but I tried to get it down to a size that would fit on a 5 1/4" floppy and when I got there, I called it a day.

If print01.sys is not included, then the files could be encompassed on a 1.2M 5 1/2" floppy.

On a 3 1/2" drive there is sufficient space for chkdsk.com, a modest size editor (I use Qedit's Q.exe which is only about 48K) and there is still quite a bit of space left over.

In case you haven't noticed it you can now include in config.sys a command (for example) call=c:\os2\xcopy.exe c:whatever d:whatever or what have you. It is very useful to back up the \DESKTOP and \os2\*.ini files on the fly. This is noted in the Manual.
