I am trying to install a 2nd connor 3104 100 MB IDE hard disk on my
386 machine. Unfortunately I do not have documentation on the drive
jumpers. The drive has 4 jumpers labelled as follows:
___
HSP
_
C/D - this is drive select
___
DSP
ACT
I have gotten the host adapter to recognize that drive d: is on the bus and
attempt to access it but it does not work. I checked out the drive and it
works as c:. According to my host adapter docs, nothing needs to be changed
on it. Any info would be appreciated. Please reply directly.
Thanks,
Ken

To set up as Drive 0, jumper HSP, CD, and DSP (ACT is for the LED, I think). Then set the second drive with NO jumpers. The first action enables the Conner as a master drive and the second as a slave. You're on your own to get the LED thing right. It appears that the first partition on the second drive will become D, with the rest following the last partition on the first drive. -- Of all the things I've lost, I miss my mind the most. halcyon!ralphs@seattleu.edu

This is copied without permission from the Conner manual: HSP, when jumpered, connectes the -HOST SLV/ACT signal on the interface to ground for systems that require the slave drive to provide -SLAVE PRESENT signal in a two-drive system. C/D is the address jumper. When jumpered, the master (or C drive) is selected. When open, the slave (or D drive) is selected. DSP, when jumpered, indicates to the master drive that a slave is present. In a two-drive system, this jumper option must be installed in the master, or C drive. The last jumper, ACT, connects the -ACTIVE signal to the -HOST SLV/ACT signal on the interface. This signal provides tha capability to drive an external LED. An external current limiting resistor is required. As an alternative, an LED may be connected between J4, pins 1 and 2. This would provide both an open collector drive signal and a current limiting resistor connected to +5V respectively. The following table shows what the jumper settings whould be for various system configurations. 1 drive 2 drive master 2 drive slave ACT J note 1 note 1 C/D J J NJ HSP NJ NJ note 2 DSP NJ J NJ note 1: In a two-drive system, it is possible to drive one LED with both drives. An external current limiting resistor is required. note2: If the drive is connected to a host that reauires that the signal -DRIVE SLAVE PRESENT be supplied from the slave drive via the interface signal -HOST SLV/ACT, then this jumper must be installed. If this jumper is installed, the ACT jumper must not be installed because the jumpers are mutually exclusive. -- Al Weiss alz@tc.fluke.com 206-356-5252 John Fluke Mfg. Co., Inc.

I have a Conner 3204 (200M) IDE drive which I inherited with no doc. Could anyone please send mail about the info I need to put in the AT CMOS Setup? (No. of heads/ cylinders/ sectors etc.). I did input some arbitrary (but seemingly logical) combinations and it works, but shows up as less than (about 194M) 200 M total space. Thanks
