TITLE: SupraRAM problem

Hayalp any or all you big noises out there :-)
I have just fitted the Supraram 8up board in my clunky old A2000,
which also has a clunky old 2090 card (see resume). The board has 8mb
of ram, and passes all its test just fine. BUT I can't get my hard
disks to mount without disabling all my fast ram first. Then, when I do get
the winnies up and away, they just write crap instead of files during 
operations such as disk copy. (They read ok). All this until I kill
the extra memory... WTF is wrong here... I have tried both the ram
card and the 2090 in different slots, to no avail....

Also, I've found a chip which came with the 2090, along with instrucvtions
which tell me to put the chip into socket U5, sadly socket U5 is a 14 pin
socket and the chip is 24 pin... Anyone else done this mod on a 2090 ?
