It certainly works fine here. It's either a problem with
running-order, or some conflicting auto-program/accessory. This is how
my auto-folder looks like when I run MagiC with TK5:



I only have two accessories, ZControl and ST-Guide. The problem can
also be FastRAM-related, how much FastRAM do you have? And in which
slot(s)? I have 32Mb in the first slot (the one closest to the AB
expansion-port) and 16Mb in the second slot. At first MagiC wouldn't
boot if the second slot was enabled (magxboot crashed at the second
boot), but now it seems to work fine.

And which harddisk-driver do you use? I boot directly with HD-Driver
6.30, this works perfectly for me. Some people prefer to boot with
AHDI and put HD-Driver in the auto-folder, you should try that too.
And don't forget to disable the XFRB-option if you use HD-Driver!

Probably best for MagiC. TK 5 is much easier to set up and much more
reliable with other stuff like TOS or MiNT though.

No problem, just remove the lead from Nemesis to the DSP and use your
own oscillator. I have a 50MHz oscillator installed, which means that
the DSP runs constantly at 50MHz. It has done so for almost two years
now without one single problem. Highly recommended!

BTW. does this happens only under MagiC? If this is the case it might
be MagiC's fault and not the DSP. On my Falcon MagiC crashes the first
time the DSP is accessed, after a warm reset it works fine. Don't ask
me why...
