!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! There is explicitly NO WARRANTY that the given settings are correct or harmless. (I only collect, I do not check for myself!!!). There is always the possibility that the settings may destroy your hardware! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Since I hope however that only well-minded people undergo the effort of posting their settings the chance of applicability exists. If you should agree or disagree with some setting, let me know immediately in order to update the list.
If you possess a HD not mentioned here of which you know BIOS and/or jumper settings, please mail them to me for the next update of the list!
Only IDE (AT-Bus) Harddisks will be accounted for. If not specified the Landing Zone should be set equal to the number of cylinders. If not specified the 'Write Precompensation' should be set 65535. (There are BIOSes that don't even ask for it). On most IDE disks these values are dummies, relicts from old MFM times.
The capacity given here is sometimes in Megabytes (1000000 bytes) and sometimes in MB (1048576 bytes). Don't worry! The only right way to calculate the capacity is
cyl * heads * sec/tr * 512
which gives the capacity in bytes! Dividing by 1000000 or 1048576 gives the capacity in Megabytes or MB respectively.
If you get problems when installing 2 HD's with correct BIOS and jumper settings, try to swap drive 1 and 2, often that helps.
Please don't flame me because of the 'layout' of the list. Since the available information is so strongly varying I often only pack _YOUR_ mail to me into the list. If someone feels encouraged to improve this, I would be glad to receive a 'lifted' version. But there should be all info contained!
Since the list is rather long, I give here a summary of all drives described therein.

Comment concerning CP3000 jumpers:
According to your list, all Conners should be 2 or 3 jumpers only. That's why I'm puzzled with the 4-jumper Conner CP-3000. In addition to the common jumpers present in Conner - C/D, DSP & ACT, there is an extra one: HSP By trial and error, HSP seems to follow DSP setting.
"When I installed a Conner CP3204F (203 MB) as master and a WD Caviar 2200 (203 MB) as slave, both with and without the "CP" jumper, the Caviar had seemingly normal behaviour. However, when doing writes to the Caviar, once in a while it would overwrite directories etc. Using FASTBACK was almost impossible."
"The workaround is to install the Caviar as the master, and the Conner as the slave."
and:
information: I am slaving a Conner CP3000 40Meg to a Western Digital Caviar 2200 212 Meg.
the results: I first found out that pin 1 on the CP3000 was LABELED INCORRECTLY on the PC board....had to flip the IDE cable (which made the cable install much more cleanly- no flips....shoulda been my first clue that something was not correct, oh well)
next: I had to DOS-format the CP3000 ALONE on the PC system before it wanted to work with the WD caviar.... weird also: the WD Caviar is partitioned: C:\ was the first 100 Meg and D:\ was the second 100 Meg. After the CMOS was correctly configured and the drives brought online, the PC AUTOMATICALLY assigned the drives as thus:
C:\ first 100 Meg partition on the WD D:\ 40 Meg Conner E:\ second 100 Meg partition on the WD
even FDISK reports the above.

Subject: Re: Conner CP 30254
I tried several combination and even called Conner for info on configuring two Conner drives as master (301??, a 300+ M Connder drive) and slave (30254). The jumpers that worked are:
Pins Jumpers Master 1-2 Y (factory setting) 3-4 Y (factory setting)Slave 1-2 N 3-4 Y (factory setting)
So the C/D should mape to Y/N instead of N/Y in the table.
Some notes made whilst configuring a pair of Conner IDE drives for Master/Slave operation from Hyundai Super-LT6 Laptop 386sx-20.
Final Working Configuration
Drive 1: CP3000 40 Mb Type 17 977 cyl 5 hds 17 sec/trk Pre 300 LZ 977
Verified configuration as per Grammes' list. HSP does need to follow DSP (empirically) - failure to do so produced behaviour such as LCD screen display scrambling on ROM boot.
Single, Master and Slave configurations all checked out.
Drive 2: CFA170A 170 Mb Unknown type 332 cyl 16 hds 63 sec/trk Pre --- LZ ---
Did not appear on Grammes' list. Successful configuration resulted close to that shown as Table 3 for Conner drives, as follows:
Single 2 links (not C)/D and (not A)/(?) Master 1 link (not C)/D Slave 0 links
One link is listed here as (not A)/(?) due to a hole being drilled through the (?) part of the silk screening ...
The drives worked together as either slave or master ...

Model CP342 disk (40 Meg IDE drive) Single Drive: E5, E7 jumpers IN Master Drive: E6, E7 jumpers IN Slave Drive: E7 jumper IN
In addition, this is an old disk drive. It was factory configured to use 3:1 interleave. This can cause timing problems with newer disk drives that are configured for 1:1 interleave when using the same IDE controller. The CONNER tech support person suggested I only use the CONNER drive as a SLAVE with the newer disk as the MASTER.
This configuration (MAXTOR 7345A as MASTER and CONNER CP342 as SLAVE) has now been in use for over a week and seems to be working fine.

> I was trying to set my IDE drive in the subject above to a slave drive for > A Conner 170MB drive and contacting the support company gave me this answer (which works). The factory default on SW2 is On Off Off Off Off Off (1-6). This sets the drive to be a single drive. Setting SW2 to Off On On Off Off Off makes it a slave drive. SW1 has been set to On Off Off On (1-4) all along.

There are two sets of jumpers. A set of 5 and a set of 4. With the power and IDE connector toward you, the set of 5 is numbered (left to right) J16 - J20 , and the set of 4 is numbered (bottom to top) J22-J25.
The only jumper of normal interest is J20. Jumper it for only drive in a single drive system, or master drive in a dual drive system. Remove the jumper J20 for slave drive in a dual drive system.
J19 is a dummy and may be used to store the spare shunt if the drive is configured for a slave mode.
Jumpers J17, J18, J24, J25 are factory reserved. Abnormal operation may occur if jumpered.
Jumper 22 is sync spindle enabled/disabled (open=disabled) Jumper 23 is sync slave/master (open=slave) Jumper 16 is I/O Channel Ready (open=disabled)

Technical Notes:* The WPC and Landing Zone BIOS entieres do not need a specific number for proper operation. Maxtor AT interface hard drives will ignore and override any numbers programmed.
* Drive is low-level formated with 1:1 interleave at factory, with any defects retired to a dedicated non-destructive zone. * The drive's on-board controller will auto-translate every cylinder, head, and SPT combination listed in the parameters table. Therefore, configuration jumpers J13 and J14 are not required for most AT BIOS setup applications.
* The 7080A is shipped with J17-J20 jumered and the 7040A is shipped with J18-J20 jumpered to operate as single AT IDE drives. J20 and J19 control master/slave operation.

Link Options
In order to install the Rodime Ro 3000A series drives the dumpers for the single/dual drive and LED operation on the drive need to be set as described in the relevant product specification.
In a single drive environment the drive is described as a Master.
In a dual drive environment the drives are described as a Master and a Slave. This is due to the protocal the takes place between the two drives when performing diagnostics.
There are four links, LK1, LK2, LK4 and LK5, adjacent to the 40 way interface connector. They have the following functions and are described in order as viewed from the end of the drive, with the first jumper described nearest the 40 way interface connector.
LK2: LED
When fitted, this jumper connects the LED drive to pin 39 of the interface. This allows a LED to be connected to the interface. An external current limiting resistor needs to be fitted in series with the LED when this option is selected. The value of the resistor will be dependant on the LED type chosen but will be in the range of 130 Ohms ot 220 Ohms.
LK1: Dual Drives
This jumper must be fitted when two drives are attached to a single bus. It fallows communication across the 40 way interface connector, indicating, to the Master drive, the presence of a Slave.
LK4: Master
When fitted this signifies that the drive jumpered is a Master. If there are two drives connected on a single bus then only one may be jumpered in this way.
LK5: IOChRdy
When fitted this connects the IOChRdy signal to the drive, it is fitted when the drive is used in host systems that have a higher data transfer rate than the drive i.e. greater than 4 MBytes per second when using 1:1 interleave. This jumper is not normally fitted as most hosts transfer at a lower rate than 4 MBytes per second.
There are four possible Master/Slave configurations in which a drive(s) may be jumpered:
Master, single drive with LED on interface LK2 & LK4 fitted.
Master, single drive without LED on interface LK4 only fitted.
Master, dual drive without LED on interface LK4 & LK1 fitted.
Slave, dual drive without LED on interface No jumpers fitted.
Master, dual drive with LED on interface LK4, LK1 & LK2 fitted.
Slave, dual drive with LED on interface LK2 only fitted.
The Master drive will delay power-up for approximately two seconds to reduce power surges in applications where dual drives are used.
The other connections for a LED will be found close to the 28 way connector at the other end of the drive. This LED driver is not affected by the link options. An internal current limiting resistor is on the drive for this LED driver. Refer to the product specification for further details.

The second was a Western Digital Caviar 340Mb:
WDAC2340 325.4 1010 12 55
Using the information from your document, I set up the Quantum as master and the WDC as slave. This worked fine most of the time, but when booting sometimes HDD-controller errors occured. When I switched the drives (WDC as master, Quantum as slave) it worked perfectly, as has done ever since.
Manufacturer: Western Digital Serie: Caviar Name: WDAC2420 Size(Mb): 405.6 Cylinders: 989 Heads: 15 Sectors: 56 (uses dynamic translation) Jumpers: CP MA SL
The drive runs as a slave with a WDAC2200 as master just fine.
Please note that these are the *recommended* CMOS parameters. All the disks support so-called dynamic translation, and should thus be able to work with any parameters having fewer sectors than the total number of sectors on the disk.
Now, according to the manual, the jumper settings are as follows:
Jumper CP MA SL ------------------------------------------------- Single 0 0 0 Master 0 1 0 Slave 0 0 1 Slave with Conner CP342 or CP3022 1 0 1
Maybe there are 2 kinds of Caviar's floating around:
If your jumpers read MA SL and SI then use: Jumper SI MA SL Single 1 0 0 Master 0 1 0 Slave 0 0 1
There have been reported difficulties in using WD Caviar as Master and NEC drives as slave - the other way it works.
When I installed a Conner CP3204F (203 MB) as master and a WD Caviar 2200 (203 MB) as slave, both with and without the "CP" jumper, the Caviar had seemingly normal behaviour. However, when doing writes to the Caviar, once in a while it would overwrite directories etc. Using FASTBACK was almost impossible.
The workaround is to install the Caviar as the master, and the Conner as the slave.
I had a WD pirana 4200 (212 mb) IDE drive and added a Caviar 2340 (341 mb) drive. No matter what I did with the CMOS settings, as soon as I define the D drive (as anything) and rebooted, it would hang for about 2 minutes and then report "D: drive failure". I am using an intelligent IDE controller since my AMI bios was too old to support IDE drives.
The fix was to call the 4200 the slave and the 2340 the master. All has been working fine since then.
