Retina Z3 BLT & 1MB ChipRAM
« on: November 23, 2009, 04:31:09 AM »
Hi

Just a quick question. My Amiga 4000 basically only has ~1MB ChipRAM free after booting into OS 3.9. Even after booting with a 3.1 Install Disk I still only have ~1MB ChipRAM available.

The 4000 has a Retina Z3 BLT installed and, according to the BBoAH, this card uses 1MB ChipRAM. My question is does the card take 1MB of RAM just by being installed and without drivers? I was expecting, booting from the 3.1 Install Disk, to have closer to 2MB (no drivers being loaded that I'm aware of) but it made no difference. Actually, I say that, but booting with the 3.1 Install Disk I actually had a shade less. I'm assuming this is because I have my OS 3.9 to use 'other memory' for graphics which wouldn't be the case when booting from the install disk.

This wouldn't bother me but a) a lot of WHDLoad games aren't running anymore and b) I'm concerned there may be an issue with the 4000 itself.

I did notice in the 'WhichAmiga' program that one line read '-1MB ChipRAM' or something along those lines (sorry, I'm at work and don't have the machine handy).

Any insight appreciated

Thanks
