The long number 27000000 stands for the frequency, I mean the pixelclock. I 
don't know exactly how it splits for horizontal and vertical frequencies, but 
if you increase this number the frequencies come up and to the other direction 
they become smaller. 
For me the 27000000 worked good, I became around 32kHZ/63Hz.

I have an A2000/Blizzard 060 96MB RAM/ECS 1MB Chip/PicassoIV/OS 3.1/IBM & 
Quantum HD's, ZIP-Drive/

If you have more than 32MB RAM you have to limit it by the -m option to around 
40MB, elswhere I had a problem too, with the booting.
