[RESOLVED] Win98, SCSI Devices and CD Roms

[Alex_F]

I have recently built a PC from ground up and it has experienced some unusual problems, can anyone help. The PC built is a ABIT KT7 Mobo, 700Mhz SocketA T-Bird, 128Mb PC133 ECC Ram, 32Mb DDR Geforce2 GTS Graphics Card, Advansys U/W SCSI Card, 9Gb U/W Seagate Barracuda HDD, 12x DVD Rom, 1gb IDE Hdd, HCF Internal Hardware Modem,and Soundblaster1024. Problems include freezing during games/graphic card demos and at windows startup, mouse not functioning within windows(however start a game and exit and it works?), and DVD movies of any region not playing. I have set the DVD region and still cannot play, also I noticed that windows will not allow me activate DMA on the DVDROM or IDE HDD. Any help? On another note does anyone know of any conflicts in windows 98SE to do with SCSI devices, the reason I ask is that I know windows treats DVD-CD Roms as SCSI and have noticed that it has assigned TargetID=0 and SCSI HostID=0 which is the same settings as the SCSI HDD - could this be causing a conflict?

I'm not aware of any possible issues between
your mainboard and other hardware (especially
your video card) but generally speaking it does sound like you have IRQ/ADDRESS conflicts. My Adaptec 2940UW scsi card runs
great with both 98 & 98se. One quick way to
begin troubleshooting is to remove all devices down to the video card (including
the DVD and SCSI card). You can'loosely' assume the board, cpu, ram, and video are fine if Windows runs ok at that point. Then start adding things ONE AT A TIME til the problem reappears. Make sure you open/run several apps and functions each time to get a good feel for "normal" Windows operations.

Your SCSI ID's are manually assigned using the jumpers on the device's jumper block. Generally the Controller is ID 7, Hard Drive 0 = 0 and 1 = 1, Other devices assigned to 2-6. Also be aware that SCSI gives higher priority to the lower numbered devices.
