Hi
I have a quadram quadboard clone thats fully populated and as far as I can see, set correctly but the machine only steps up to the 256K memory installed on the motherboard (the original quadboard is toast due to battery acid and a lack of enthusiasm to repair evaporated tracks)
I am aware that the XT uses a quick memory pattern test to determine the size so if there is an error in the first row its knon to think the memory has ended and stop testing I believe.
So my question is, once the POST has determined the memory size, is the memory on the quadram card still accessible for testing and does anyone have a program to do it. I can't imagine a way of locking out that portion of the memory map from being tested, but you never know. What I dont want to do is mess about swapping endless numbers of chips trying to locate duff ones.
Would Checkit do the job ? I see that is on the -0° site.
