| 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:. |
