MISCELLANEOUS TECHNICAL NOTES

There are no user-configurable jumpers on the WD1007V-MC1, all configuration is done through the firmware. Each WD1007V-MC1 board can support two hard disks. If two WD1007V-MC1 boards are installed in a PS/2 system only one drive may be attached to each controller. (i.e.: you can never have more than a maximum of two hard drives in a PS/2 system, no matter how many controller cards are installed.) The ESDI drive is always assigned to C:. If you have one ESDI and one ST506/412 drive, the MCA architecture always selects the ESDI drive as drive C:.
