124 Troubleshooting

Suggested solutions

Remove Real Mode (DOS) drivers for the DVD-ROM drive. Real mode CD- ROM drivers may interfere with proper DVD-ROM operation. Real mode drivers for the CD-ROM are only required if you wish to access the CD- ROM from DOS. Look in the CONFIG.SYS file for CD-ROM drivers that may be loaded.

Following are some examples of “DEVICE=” lines that load REAL MODE CD-ROM drivers.

DEVICE=C:\SBCD\DRV\SBIDE.SYS /D:MSCD001 /P:170,15 /V

DEVICE=c:\bin\AOATAPI.SYS /D:MSCD003

Device=C:\DEV\AOATAPI.SYS /D:mscd000

To determine if the CD-ROM driver is the source of the problem, simply edit the CONFIG.SYS file and add the letters “REM”to the beginning of the “DEVICE=” line. (e.g. REM DEVICE=CR_ATAPI.SYS /D:MSCD0001). Save the CONFIG.SYS file, reboot the system and see if the problem still occurs.

NOTE: the REAL MODE CD-ROM driver is not usually required for Windows 98 to access the CD-ROM drive. The REAL MODE driver is only required to access the CD-ROM when booting to DOS MODE.

Disable UDMA support in CMOS. Some motherboards do not function properly when the built-in UDMA support is enabled. In some cases, Windows DMA support will not appear in Device Manager when UDMA is enabled in CMOS.

1Turn on your PC, and press the Del key or the F2 key to enter the CMOS setup screens. (Different BIOS makers may use a different key; check the screen for a message that tells you which key to use.

2Disable UDMA support for all IDE devices; for example, an Award BIOS under Integrated Peripherals typically shows:

IDE primary Master UDMA AUTO < (Change to Disable.)

IDE Primary Slave UDMA AUTO < (Change to Disable.)

IDE Secondary Master UDMA AUTO < (Change to Disable.)

IDE Secondary Slave UDMA AUTO < (Change to Disable.)

Save the new settings, then exit CMOS setup.
