□ 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.
