Well i have amigaos 3.9 on my system (a1200t) and i have my desktop set at 256 colors which uses up a lot of fast ram so that could be one of the reasons, what resolution are you using on your desktop as this may also be the problem what are you using for your display?
Thanks for the reply. I'm using NTSC Hi-Res interlaced, 724x482, 16 colors. I'm displaying that on an ancient 19" Ramtek CRT with a long-persistence phosphor. It looks quite lovely, although one of my projects is to switch to a flat panel - but that's another story.
Anyway, after checking this, it says I have 1 meg. of chip free and 9 bytes of fast mem free. After switching to Lo-Res, I got 720 bytes fast ram free, 4,193,584 max, 4,194,304 in use. So I don't think the display mode is the trouble.
I then tried a "boot with no startup-sequnce". This drops me into something called the "ROM OS". Doing an avail here, I get
avail in-use max
chip 2007312 88816 2096128
fast 3322576 871728 4194304
So next I tried putting the 8-up board back in. This time (still in hi-res mode) I get:
avail in-use max
chip 1755920 340208 2096128
fast 3762112 4626496 8388608
That looks right (I guess). 8 meg. total fast ram, four of which come from the 2630 and 4 from the 8-Up. I can now do stuff like load the Ethernet but now the Bridgeboard won't start (because of the 6 meg. fast RAM limitation). Anyway, it looks like the problem is still there. I'm guessing that a freshly booted 2000 running no programs other than WB should not already be consuming 4 meg of fast ram, even running OS 3.9, yes?
Unless anyone has a better idea (there's nothing like Task Manager for the Amiga?) I guess my next step will be to try pulling the Deneb board and then the Xsurf board to see if one of them is hogging my ram.
