I am having this problem now with my Compaq presario 9564. I am runnig 2.2.6 and it only detects 16 meg and I have 24 in there. I thought it might have been because the memory I added was not "Compaq" memory or something like that. I will define MAXMEM and fix this tonite. :-) -Chris On Wed, 17 Mar 1999, Matthew D.
