For OS/2 1.2 and pre-1991 OS/2 1.3

DISK02.SYS is a replacement for the driver supplied with OS/2. If you're not absolutely certain which driver you need, it would be a good idea to copy the DISK02.SYS file now on your hard drive onto a floppy for safekeeping. Install the new DISK02.SYS file by just copying the file DISK02.SYS from the MCMaster option diskette into the root directory of your boot drive. When you reboot OS/2, the driver will load automatically.

For OS/2 1.3 with a copyright date of 1991 or later

Leave the existing DISK02.SYS in place. Copy the file OEMXLAT.SYS from the MCMaster option diskette into the root directory of the boot drive. This version of OS/2 automatically looks for the driver at boot time and, if it finds it, loads it.

OS/2 2.0 and higher

With OS/2 2.0 and higher (2.x), IBM has built-in support for the MCMaster so that the kernel finds MCMaster memory and locates itself there, regardless of where the MM memory is in the map. For this reason, the performance of "Mapped" and "Unmapped" will be about equal under OS/2 2.x.

When installing OS/2 2.x on a PS/2 Model 50 or 60 and the OS/2 installation "chokes" on the second diskette, use INSTOS2.EXE contained on the Kingston MCMaster diskette.

Follow the steps below to use INSTOS2:

1.Boot into DOS (any version) from a hard disk or floppy diskette. Be sure to boot DOS without EMM386 or any other memory manager.

2.Insert the MCMaster option disk into the floppy drive.

3.Run the program by typing: A:INSTOS2 [Enter]

4.Your screen should display the following:

This program is used to modify the way the floppy slowdown is done to assist in installing certain versions of OS/2 on some machines.

Esc to exit.

5.Insert the OS/2 Install diskette and press [Enter]. Installation will proceed normally.
