Ok, I found mail in the archive that explained what I wanted here
better,
so I got this to work with
insmod pg drive0=0x378,0,0,1,-1,0
but it seems to be slower than with the delay of 1! Moreover, it still
seems to be lots slower even when I default it like I was doing before.
So I'm really lost.
Any ideas / help hints?
I have a P-166, BTW.
