Crystal Driver Installation on XEN-PCLS and LS Pro

There has been some confusion arising from the settings of the drivers for both the LS Pro and the XEN-PCLS. This results in an error message stating that the system could not load VSNDSYS.386 due to an incorrectly specified interrupt.

The Installation modifies SYSTEM.IN and adds a section called [SNDSYS.DRV] These are different for the LS Pro and the XEN-PCLS and should look like the following.

LS Pro
SYSTEM.INI

[sndsys.drv]
Duplex=Full
SingleModeDMA=0
DMABufferSize=36
OldMSDosGameCompatibility=0
WatchMSDosExec=0
BlasterSupport=SWEmulation
Msft Hardware=0
Msft Support=1
Auto Select=0
Midi Play=0
EnableAutoAcquireOPL3=0
DMA 0=1
DMA 1=1
DMA 3=1
Default DMA=1
I/O 530=1
I/O 604=1
I/O E80=1
I/O F40=1
Default I/O=530
IRQ 7=1
IRQ 9=1
IRQ 10=1
IRQ 11=1
Default IRQ=7
IOAddress=530
DMAADC=0
DMADAC=1
Interrupt=11

[opl3.drv]
portFM=388
int=9

XEN-PCLS
SYSTEM.INI

[sndsys.drv]
Duplex=Full
SingleModeDMA=0
DMABufferSize=36
OldMSDosGameCompatibility=1
WatchMSDosExec=1
BlasterSupport=SWEmulation
Msft Hardware=1
Msft Support=1
Auto Select=1
Midi Play=1
EnableAutoAcquireOPL3=1
DMA 0=1
DMA 1=1
DMA 3=1
Default DMA=1
I/O 530=1
I/O 604=1
I/O E80=1
I/O F40=1
Default I/O=530
IRQ 7=1
IRQ 9=1
IRQ 10=1
IRQ 11=1
Default IRQ=7
IOAddress=530
DMAADC=0
DMADAC=1
Interrupt=7

[opl3.drv]
portFM=388
int=0

The settings for the LS Pro are fixed, but with the XEN-PCLS it is possible to modify the base memory address and interrupts, but only with reference to the switch settings on the feature card.
