I was able to get my Vulcan 20 to work with larger drives by replacing the
EPROM with a Vulcan Gold EPROM. Here are the drives I've gotten to work with
it, so far:
Conner CP30084 80meg 1/3 height C/H/S: 903/4/46
Conner CP3104 100meg 1/2 height C/H/S: 1547/4/33
Those were used in Compaq computers.
It appears that the Gold upgrade allows more Cylinders, but still limits the
heads to 4. I tried some drives in the 125 meg range with 8 and 16 heads,
no go. Also a 5 head drive would not work.
I'm using Partition.Manager 2.0, anyone know if there was a newer version?
There is a rumor that typing "AE" will let you change the CHS parameters,
but with my hardware and firmware that just re-partitions the drive with the
parameters the program comes up with.
The software gives an error message and quits when the drive exceeds 4
heads, so there is no chance to input parameters.
