Thanks, I suspected it had something to do with this. Half a meg seems kind of steep for the two partitions I need to leave active... To my knowledge I didn't tweak the buffers in HDToolbox when I set the machine up, but I don't remember. Would it be safe to lower the buffers from HDToolbox on the fly (without data loss)? Sorry for the stupid questions, it was a while since I last installed an Amiga.
Eating half a meg does seem excessive, but you probably have a lot of buffers set. Let's say you have 300 or more buffers set on each partition....well that's no problem because when you boot with no startup sequence, just type "addbuffers dh0: -299" and it will leave you with 1 buffer...which is the minimum you can have (just write add buffers -3000 if you like, it cuts them down to minimum anyway).
Yes, you can change the amount of buffers in HDToolbox/HDInst Tools for each partition and you will not loose your data, it simply adjusts the size of the buffer (requires reboot however).
You could edit your startup-sequence so that if a 68020 processor is detected then it will do this for you (put it at the beginning of your startup-sequence).
One question I have though is why would you want to disable your Blizzard? Are you having problems with WHDLoad?
The problem you will have is that 2MB chip just doesn't cut it with WHDLoad...you need 2MB chip for AGA games/demos (1MB chip for A500 stuff) but on top of the chip requirements you will need 2MB FAST RAM or more.... to load the kickstart or to preload the disks, and some slaves require fast ram anyway as they relocate some routines to fast ram. So your 2MB idea just isn't going to work I'm afraid. Yes, some stuff will work, but it'll be the A500 512k games/demos most likely.
