[comp.sys.ibm.pc.hardware] Need AST RAMpage technical info

fredriks@cbnewse.att.com (lars.fredriksen) (06/29/90)

Hi!
	I am looking for technical information of how to PROGRAM the
	AST RAM page. By disassemlying their REMM driver, I come across
	things that are not mentioned in the 1986 document that I have.

	For instance, the REMM driver writes stuff to the option switch
	port. The driver also writes stuff to port 0x2c9, but no such
	port is documented to be for the RAM page, nor does any on my
	technical references for the IBM PC XT, refer to such a port.
	
	Any ideas anyone??

	Please reply by e-mail


	Sincerely

		Lars Fredriksen


PS: 	The reason I want to program the RAM Page is to get it working under
	MINIX.
