== Troubleshooting Ports and Windows ===== SYSTEMS FINDS TWO GAME PORTS, TWO WAV OR SOUND DEVICES ===This system has a sound card and a modem as two seperate cards but they are connected by an audio cable.System kept finding two of each device, solution:under INTERGRAGED PERIPHERIALS in award bios change:*PCI slot IDE two channel: DISABLED*Onboard Gameport: DISABLED*Onboard Parallel Mode: ECP+EPP (bad)*Onboard Parallel Mode: EPP (bad)*ECP Enhanced Communications Port*EPP Enhanced Parallel Port*SPP Standard Parallel Port=== SYSTEM FREEZES DURING WIN95 LOADING, RUNS FINE WHEN REMOVE MODEM ===I've seen this with the Logicode 8bit modem card. The system would not load win95 or would return "invalid operating system". When themodem was removed, it booted fine. solution:*adjusted following settings in cmos*Onboard Serial Port 1: com3/3e8*Onboard Serial Port 2: com2/2f8*before the Port 1: was set to com1, causing a conflict with the modem on com 1. Usually this just makes the PnP modem not recognized by windows 95, but sometimes it actually locks up the maching on boot.=== MODERN PCI SOUNDBLASTER LEGACY SUPPORT, NO SOUND IN SOME MS-DOS GAMES ===updated: Sat Feb 3 11:28:26 CST 2001These are general tips for configuring most Creative Labs sound cards to workfor legacy support of audio in games (such as DOOM).*.) usually modifying DMA and IRQ settings in the autoexec.bat file is useless,since the software drivers will change them back on reboot.*.) usually you can not modify IRQ and ADDR settings from windowze. "This resourcecannot be modified" will appear if you try from the system properties.*.) modification of the sound card IRQ can best be accomplished from the bios. Disablean IRQ or change it to ISA/Legacy and the PCI card will not be able to use it and thusrelocate to another available IRQ, sometimes even moving other devices out of the way.*.) the afore mentioned is NOT NECESSARY to get the IRQ you desire for your legacyMS-DOS game such as DOOM. The Windowze PCI IRQ is NOT THE SAME as the legacy device IRQavailable in MS-DOS. Goto a command prompt and type "set" to view those settings or onmany Creative Labs cards you may view it from the device properties "Legacy Audio Device"under Windowze. A tab labeled "DOS Application Settings" will display those resources.*.) so far I have found no way to modify the "DOS Application Settings" including editingthe set line in autoexec.bat (which just resets such as was suggested above).*.) observe the 8 bit DMA IRQ and use it for old games such as DOOM. DOOM defaults toIRQ3 for this, but often the new SB legacy suppt is set to IRQ1.*.) Do not use the 16bit IRQ unless you know for sure the game supports it; DOOM doesn't.*.) You may use midi for the game's music by selecting the same address as assigned tothe port. This seems to work fine in DOOM as well as just selecting Sound Blaster.[[Category:Windows]]
