B-4 SB Emulation in MS-DOS/ Window 95/98
4. Double-click Creative Miscellaneous
Devices, and then double-click Creative
SB PCI512 SB16 Emulation.
5. Click the Resources tab.
You can use the information in the resource list
to help you configure MS-DOS games for use
with the SB PCI512 card.
The resource list may show three entries of
“Input/Output Range” and two entries of
“Direct Memory Access”. They correspond to
the sequence of entries in Table 1 and Table 3.
If the number of entries do not match, a good
estimate of the identity of the device is its I/O
address or DMA channel.
To find the current SB PCI512 SB16
Emulation resources in MS-DOS mode:
1. Switch to your SB PCI512 DOS driver
directory, that is:
C:
\PROGRA~1\CREATIVE\SBPCI512\DOSDRV
2. Type SBECFG and then press <Enter>.
The MS-DOS driver
SBEINIT.COM must be running
for SBECFG.EXE to work
properly
.
Some older games may have difficulty
detecting the SB PCI512 card at certain
resource settings. Typically, these games
would expect the card to be at a fixed set of
resources and would fail to load if those
resources are not detected. If you have older
MS-DOS games that do not work properly, try
changing the SB PCI512 SB16 Emulation
configuration. Use the following as a guide:
Problem: Sound Blaster emulation is not
recognized.
Resource: Try switching the SB Emulation
IRQ between 5 and 7, use DMA
channel 1, use SB interface port
220.
Problem: The MPU-401emulation is not
recognized.
Resource: Try using Port address 330.
Selecting the Best
Audio Options in a
Game
Most MS-DOS–based games that provide
sound have some procedure for audio setup.
These procedures generally present you with a
list of popular audio cards or audio devices
from which to choose.
The methods used by games to present audio
options can vary greatly. Some may present a
single choice that corresponds to a particular
audio device, that is, Sound Blaster, Sound
Blaster 16, Roland Sound Canvas, and so on.
Others will provide an option for music and
digital audio separately; for example, General
MIDI music with Sound Blaster digital audio.
In such a case, there are often two separate
menus to configure.
Some games allow you to set the MIDI port
address and IRQ for music and sound. Make
sure that these settings correspond to the
values displayed by SBECFG.EXE
or the
Resources tabbed page of the Creative SB
PCI512 SB16 Emulation Properties dialog
box.
There are games that offer MPU-401/Roland
(General MIDI or MT-32/LAPC-1) as an
option. Often these games allow you to set the
MIDI port address. Make sure that they match
the MIDI address in the Resources list on
Resources tabbed page of the Creative SB
PCI512 SB16 Emulation Properties dialog
box. The same values can be found under
“MPU-401 (General MIDI, Roland
MT-32/LAPC-1) Emulation”, displayed by
SBECFG.EXE in MS-DOS mode. Remember
to enable the MT-32 MIDI patch with the
SBEMIXER program if you select Roland
MT-32
or LAPC-1 for music.
Music Options
Most MS-DOS games offer a menu choice for
sound when they start up. If you have a choice
between General MIDI and MT-32, always
choose General MIDI, since it will provide
you with the best sound quality. If you need to
use MT-32, you must first switch from the
General MIDI instrument set (the default) to
the MT-32 instrument set using SBEMIXER.
Be sure to switch back to the General MIDI set
when you are finished using the MT-32
instrument set.
