[comp.sys.ibm.pc.hardware] Help: installing second harddisk

dz@irst.UUCP (Massimo Dal Zotto) (05/13/91)

I have a PC with a Quantum 40 AT harddisk (40MB, IDE controller) and now I
would like to install a second harddisk, a second hand Miniscribe 8051A (40 MB
IDE controller,dated Jan 1990), but I have no documentation on jumper settings.
The documentation for the controller card says that it supports 2 floppies and
2 harddisks, the cable, 40 pin non-twisted with 2 connectors, is ok, the cmos
setup has the 2 harddisks configured, but when I switch on the PC, or it waits
for a very long time before issuing an error message, or it hangs completely,
depending on the jumper settings.

The Quantum has 2 jumpers, named DS and SS, with this meaning (I believe):

	DS short, SS open	unique drive, this is current setting
	DS short, SS short	master drive
	DS open,  SS open	slave drive

The Miniscribe has a group of 10 pins, with a jumper between 1 and 3:

	10  8  6  4  2
	 o  o  o  o  o
	
	 o  o  o  X==X
	 9  7  5  3  1

With these settings I am able to install either one of the two drives but not
both.  I would like to know how to configure the Miniscribe as secondary
harddisk and if the settings for the Quantum are correct.
Any help will be greatly appreciated.
