Micropolis 2200A-Series

CONFIGURATION INFORMATION

Configuration and Jumper Options

Master/Slave Selection The interface allows up to two drives (a Master) and one Slave) to be attached to the IDE bus. This is selected by jumpers W1 and W2, as follows:

  Jumpers	Description

W2	W1
in	in	Drive emulates both Master and Slave
in*	out*	Drive is Master, Slave is present
out*	in*	Drive is Slave
out	out	Drive is Master (factory default configuration)

* Note: The asterisked settings for W1 and W2 are shown incorrectly 
in the Drive Information Booklet, Document 110781 Rev A.

For any of these configurations, Micropolis highly recommends the use of OnTrack Disk Manager software to auto-configure the drive without defining the drive to the system BIOS. Disk manager will handle partitioning and formatting the drive. Drive emulates both Master and Slave: Specifies that one drive can emulate both the Master drive (Drive 0) and the Slave drive (Drive 1). When the drive is configured as both the Master and the Slave, the Master's (Drive 0) capacity is set to 1024 logical cylinders, 16 logical heads, and 63 logical sectors. This setting yields 528,482,304 bytes. The Slave's (Drive 1) capacity is set to the remaining storage on the disk drive. For this configuration, the recommended drive type setting in the computer's CMOS memory is as follows: Model 2205A: Drive 0: 1024 logical cylinders, 16 logical heads, 63 logical sectors.
Drive 1: 26 logical cylinders, 16 logical heads, 63 logical sectors. Model 2210A: Drive 0: 1024 logical cylinders, 16 logical heads, 63 logical sectors.
Drive 1: 867 logical cylinders, 16 logical heads, 63 logical sectors. Model 2217A: Due to the inability of some system's BIOS to address over 1024 cylinders, the Model 2217A requires the use of OnTrack Disk Manager software to partition the drive.
Drive is Master, Slave is present: Specifies the Master drive (Drive 0) when two drives are used in a system. The other drive is Slave. Drive is Slave: Specifies the Slave drive (Drive 1) when two drives are used in a system. The other drive is Master. Drive is Master: Specifies the Master drive (Drive 0) when one drive is used in a system.
