So...If I turn off DMA on HS SCSI i'll get 5Mb RAM?

I had it in a ROM01 GS, and it worked fine. Gave me 4096+128K+256K.
Diagnostics worked, and passed all memory fine.

Then I acquired this ROM03 GS (Rom3,kb,mouse,monitor,IWII printer, 1 ea.
3.5/5.25
price: free! hehehe), moved my stuff over, expecting to get 5Mb.


PS Thanks for all the help.
