[comp.sys.ibm.pc.hardware] Info on AMI BIOS setup

eejsc@marlin.jcu.edu.au (John Croft) (06/24/91)

I have an Optima 386sx@20Mhz 2Megs Ram, 16K cache, Maxtor 7120AT
The BIOS Title at BootTime is:

	AMI 386sx-BIOS (c) 1990 AMI, for MB-1320-CH
	(c) AMI
	EOPX-1223-101090-KF

The MB-1320-CH is the designation of my motherboard.

The board uses a OPTI 82C282 chip(set). I've put the bus speed to 10Mhz
(R14,b0 = 1) and that speeds it up! Any other tips for this machine?

My question is: What does these two entries in the CMOS setup mean?

	Video BIOS shadow  : Enabled
	Scratch RAM option : 1                 <------ this one?
	Main BIOS shadow   : Enabled
	256KB memory reloc.: Enabled           <------ and this one?
	Cache Memory       : Write throught    (sp!)

I know what the shadowing does but the two others, well, no idea!
