NOTE: Subtests 02 and 04 are for Enhanced Port Replicator . For procedures on those
subtests, refer to Enhanced Port Replicator manual.
Subtest 03 RGB monitor ID test
Connect a wrap around Board to the external monitor port to test the RGB
monitor ID.
Subtest 06 ZV Port wrap around
Use the PC Card/ZV Test Card (Rev.B or higher) to conduct the test. The
video and audio interfaces will be tested. When the video test is initiated, the
board automatically writes data AAAAh and 5555h alternately to address
A000:0000h. The data written first is determined randomly, and has no effect
on the validity of the test.
After the video test is run the audio interface is tested. The test emits 1kHz
sine wave sound on the left speaker and 2kHz sine wave sound on the right
speaker.
