- SYMPTOMS
- ========
-
- Data transfer can occur very slowly when you are reading a video CD in an
- IDE CD-ROM drive if the following conditions are true:
-
- - The IDE CD-ROM drive is configured as the slave device on an IDE
- channel, with another device (such as a hard disk) configured
- as the master device on the chain.
-
- - You are using protected-mode drivers to access the IDE devices,
- including the CD-ROM drive.
-
- For example, playing an MPEG file from a video CD can cause the computer
- to seem to stop responding (hang) due to the very slow rate at which data
- is being read from the CD.
-
- CAUSE
- =====
-
- There is a problem in the Ios.vxd file that causes excessive seeks on data
- requests from the CD-ROM drive under these conditions. This results in
- degradation in the rate of data transfer from the drive.
-
- RESOLUTION
- ==========
-

- corrects this problem. The file is:
