Re: Problems booting on AlphaPC164LX

	Hi!

I had similar problems with an AlphaPC like yours. The trouble turned out
to be the RAM. Linux for some reason couldn't handle the 256M of RAM
when both banks of SIMMs were full. When we put 256M of RAM all in one
bank (two 128M modules), Linux worked (and still works) great. We tried
RAM from several different manufacturers and of several different size, 
but the problem remained the same all the time. Perhaps someone can 
comment on this too.
