Two reasons:
1-I had configured USB and both serial ports, and forced SCSI and video
to specific unshared IRQ's, and that meant the only unused IRQ's
available for the sound card were 9 and 15. I've since changed the BIOS
to allow it 5 and 9, by disabling IRQ 3 and allowing USB to use it
instead, and setting 5 as reserved for ISA.
2-OS/2 doesn't find it necessary to reserve IRQ 15 when there is only
one IDE device in the system and the secondary IDE controller is
disabled to free IRQ 15 for something that wants or needs it.

This Award BIOS doesn't seem to like permissive PCI IRQ sharing, only
sharing to specific slots, like 1 & 4. I once tried two Symbios SCSI
cards that use the same driver, and no matter how I set the BIOS or how
I rearranged the cards in the slots, it simply would not allow the SCSI
cards to share an IRQ.

I never tried it the DOS software, and the ISA card is jumperless. No
windoze here, and don't use DOS enough to bother making sound work in
it. Sound card came only with a CD, which is a PITA in DOS. OS/2
installed the ISA sound drivers with no fuss or lockups.

No cards have manual jumpers.
Here's the OS/2 CONFIG.SYS entry:
BASEDEV=CWAUDIO.SYS /N:BSAUD1$ /X1:100 /X2:100 /LCAPT:X1X2 /V /I:9 /S:220
Broken down, this means:
/N:BSAUD1$ name of PDD
/X1:100 AUX1 unmute/gain (usually Line-in)
/X2:100 AUX2 unmute/gain (usually CD-ROM in)
/LCAPT:X1X2 Line-In record source X1, X2, *X1X2, L (X1X2 is mixed aux1+aux2)
/V Verbose Display
/I:9 Codec IRQ
/S:220 Sound Blaster Port *220, 240, 260, 280, NONE
Here are the rest of the possible settings from the OS/2 driver

/MOM:<0,1> Mono out mute *0 (audible)
/XCTRL0:<0,1> XCTRL0 Pin set System specific. Sometimes used to
/XCTRL1:<0,1> XCTRL1 Pin set control power to amplifier. On IBM

Sept 1999 Award BIOS and relevant devices are as follows:
Screen 2:
PS/2 mouse function control -> enabled (Logitech optical wheel mouse)
Screen 3:
OnChip USB -> enabled (nothing currently connected)
Screen 5:
IRQ 5 -> legacy ISA
Assign IRQ for USB -> enabled
Assing IRQ for VGA -> enabled (ET6100)
Slot 1 use IRQ -> 10 (sym53c8xx) (slot adjacent to empty AGP slot)
Slot 2 use IRQ -> 3 (Realtek 8139)
Slot 3 use IRQ -> 11 (ET6100)
Slot 4 use IRQ -> AUTO (empty; reserved for additional storage controller)
Screen 8:
Onboard serial 1 -> 3F8/IRQ4 (external modem when it's powered on)
Onboard serial 2 -> disabled
Onboard parallel port -> 378/IRQ7 (local printer)
Onboard parallel mode -> ECP/EPP
ECP mode use DMA -> 3
On bootup, BIOS reports IRQ's:
IDE 14
USB 3
SCSI 10
Network 3
Display 11
ACPI 3
ISA WSS/SB 9 DMA 1,0
When booted, OS/2's hardware manager reports:
IRQ DMA
psaux 12
sound 9.15 3,1
DMA0
DMA1 4
floppy 6 2
IDE0 14
keyboard 1
parallel 7
PIC0
PIC1 2
RTC 8
serial0 4
USB 3
VGA
OS/2 has never listed the Realtek 8139 in hardware manager.
There are other devices listed, but none have IRQ or DMA
allocations. I/O addresses are listed. If you want those
too, let me know.
I tried to find something to list resources in Linux using
apropos, and had no luck. What do I use at the cli to list
them?
