list of ide harddisk specs configuration of ide harddisks last update collected by carsten grammes ph hucg rz uni sb de and published regularly on comp sys ibm pc hardware 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 there are bioses that don t even ask for it another statement maybe right ide harddisk don t have precomp and lzone the precomp is a built in parameter and lzone isn t used because most if not every ide disk has autopark the jumpers names are given as printed on the hd s board often only a jumper number jp means the jumper a zero means that the jumper is left open a one means that the jumper is closed c o n n e r conner peripherals drive geometry ide at conner

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 lk lk lk and lk adjacent to the 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 way interface connector lk led when fitted this jumper connects the led drive to pin 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 ohms ot ohms lk dual drives this jumper must be fitted when two drives are attached to a single bus it fallows communication across the way interface connector indicating to the master drive the presence of a slave lk 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 lk 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 mbytes per second when using interleave this jumper is not normally fitted as most hosts transfer at a lower rate than 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 lk lk fitted master single drive without led on interface lk only fitted master dual drive without led on interface lk lk fitted slave dual drive without led on interface no jumpers fitted master dual drive with led on interface lk lk lk fitted slave dual drive with led on interface lk 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 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
