!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 
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!

to run SETUP, FDISK, and DOS FORMAT. 
 
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.

BIOS SETTINGS 
 
BIOS setting for the M2614ET in my system is 667 cylinders, 33 sectors 
and 16 heads. 
 
> 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 6 switches on the switch block on these drives.  Only 4 of  
them have a use that I am aware of (from my M2624T manual):

                    Enabled         SW1-1 ON 
 
I have no idea about the function of SW1-2 and SW1-6.  The values  
listed with a (*) are the factory default settings.

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. 
   I 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.

(1) In a two-drive system,it is possible to drive one LED 
    with both drives. An external current limiting resister is required 
 
(2) If the drive is connected to a host that requires that the - DIRVE SLAVE 
    PRESENT be supplied from the slave drive via the interface signal - 
    HOST SLV/ACT, then this jumper must be installed, the ACT jumper must 
    not be installed because the two jumpers are mutually exclusive

The jumpers settings I got from Toshiba.  They refer to  
connector PJ10, the 1st being the pair of pins closet to the 
outside of the drive and the 6th being the pair closest to 
center of the drive.

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.
