You can use the CMOS system Setup program on a CompuAdd 386 to set options useful in troubleshooting possible problems when running Microsoft Windows.
Functions that can be changed include the setting for shadow RAM and the protected mode operation of the 80386 microprocessor.
To activate the CMOS Setup program, press CTRL+ALT+ESC after the machine boots.
The CompuAdd 386 can shadow the system BIOS and video BIOS in fast 32-bit RAM. You may want to temporarily disable this feature to test with Windows or to regain a small amount of memory for programs.
For example, if the system needs expanded memory for applications, but it cannot set the page frame in the upper memory area, then a good approach is to disable the system and video BIOS settings individually to troubleshoot this kind of problem.
CompuAdd 386 Models 316S or 320SIf you have a CompuAdd 386 model 316S, you may receive the following error message:
where <x> is standard or enhanced. This message may appear even though nothing is being loaded in the CONFIG.SYS or AUTOEXEC.BAT file.
Cannot run Windows in <x> mode with currently installed protect mode software
The CMOS Setup program for the CompuAdd 386 model 316S shifts the processor into protected mode if the "XFEATS" (Extra Features) option is enabled. This feature needs to be disabled to run Windows in standard or enhanced mode.
Please contact the manufacturer for an explanation of the Extra Features (XFEATS) option and for further assistance in using the CMOS system Setup program.
