NVCPQDSK is for use with mirrored or duplexed disk configurations that require maximum performance.

NOTE: Execution of the NetWare UNMIRROR command terminates write duplication on mirrored or duplexed drives. The UNMIRROR command has no effect on which disk drive is in use. NetWare must be reinstalled in order to change from one fixed disk drive to another.

To prepare the 1:1 Interleave Buffered ESDI External Fixed Disk Drive Controller Board, complete the following steps:

1.Select the primary or alternate disk con- troller address and the IRQ level using the appropriate switches. Select IRQ11, IRQ12, or IRQ15 for the external fixed disk con- troller operating as a secondary channel.

NOTE: If you are using the external fixed disk drive controller and have the internal fixed disk drive controller disabled, select IRQ14. If you are using two fixed disk drive control- lers, one must be defined as IRQ14 and the other can be IRQ11, IRQ12, or IRQ15. (Most other COMPAQ fixed disk drive controllers use the primary address and IRQ14).

2.Verify that the interrupt level chosen does not conflict with interrupts for other installed devices.
