IBM 5162  -  GSETUP

Motherboard BIOS configuration of the 5162 is referred to by IBM as SETUP.  Some people refer to it as CMOS SETUP.
IBM's way of performing SETUP on the 5162, is to use the 'Diagnostics for IBM AT and IBM XT Model 286' floppy.

The use of the third-party DOS program GSETUP.EXE is an alternative.

If you decide to use GSETUP.EXE, then note the following known problems/issues:


1. A design flaw in GSETUP is that it expects the existing expansion memory setting in the CMOS/RTC chip to be 0 or a multiple of 128 KB (which is the norm).
If, for whatever reason, the existing expansion memory is not 0 or a multiple of 128 KB, then you will probably discover that you cannot set the expansion memory setting to the figure that you need it to be.
If you are in that situation, you need to clear the CMOS/RTC chip by performing the procedure here, and then rerun GSETUP.
