[comp.sys.ibm.pc] AT memory expansion problem

mesmo@Portia.Stanford.EDU (Chris Johnson) (02/27/89)

	Hi there - I recently bought a 1/2 meg of memory to round
	out my AT a bit (TC 2.0 sucks air with a mere 512) and have
	experienced a small problem: it doesn't work.  And since the
	store I got it from closed their doors permanently shortly
	after my puchase, I am without technical advice.

	With all of the configuration switches set properly (I think), and
	proper setup recorded in battery-backed mem, I get this
	message at boot time:

		Memory write/read failure at 080000, read EBEB expecting F7F7
		 Decreasing available memory
		Memory write/read failure at 100000, read F7F7 expecting EFEF
		 Decreasing available memory

	Options:

		(1) memory is defective

		(2) memory is too slow for my machine


	What else?  I am a hardware peon, and have no idea what's going 
	on here.  Do I need some sort of driver?  Where does EMS figure
	into this?

	Please respond via email; thanks loads in advance
