Appendix B Test Descriptions SCSI CDROM Read Test This test reads logical blocks from the SCSI CDROM. If the starting logical block number and end logical block number fields are not specified, the test starts reading from block 0 and terminates at the last block of CDROM. This test will fail if an audio CD is inserted inside the drive. Misc Tests The Misc Test Menu includes testing of the serial port with a series of tests designed to ensure complete functionality is present. A similar specific set of tests is present for parallel ports. Serial Port A maximum of four serial ports (COM1 through COM4) are tested. All parameters i.e. number of data bits, number of stop bits, parity type etc. can be individually selected for each port. The tests that are performed on the serial ports include: Register test, Interrupt ID test, Internal loopback test, Line status test, Modem control register test, Data transfer test (at baud rates from 300 BPS to 115.2KBPS and FIFO test. Parallel Port A maximum of three parallel ports (LPT1 through LPT3) are tested. The test parameter window asks the user whether a printer or a loopback plug is connected. If these are not connected, only the register read/write test is performed. Otherwise, the following tests are performed: Register test, IRQ activation test, Pattern printing, Bold letter printing, Compressed mode printing, Printer form feed test, and ECP test. Video Test The Video Test Menu includes functional exercising of the video memory. Video Memory Test The Video Memory Test checks the base 256k of video memory for integrity by performing a memory pattern test. IDE CD-ROM The IDE Tests include exercising of the CD-ROM tray response, data, and audio if present. IDE CD Data Test This test reads logical blocks from the CDROM. If the starting logical block number and end logical block number fields are not specified, the test starts reading from block 0 and terminates at the last block of CDROM. This test will fail if an audio CD is inserted inside the drive. 73

SCSI CDROM Read Test
This test reads logical blocks from the SCSI CDROM. If the starting logical block number and end logical
block number fields are not specified, the test starts reading from block 0 and terminates at the last block of
CDROM. This test will fail if an audio CD is inserted inside the drive.
Misc Tests
The Misc Test Menu includes testing of the serial port with a series of tests designed to ensure complete
functionality is present. A similar specific set of tests is present for parallel ports.
Serial Port
A maximum of four serial ports (COM1 through COM4) are tested. All parameters i.e. number of data bits,
number of stop bits, parity type etc. can be individually selected for each port. The tests that are performed
on the serial ports include: Register test, Interrupt ID test, Internal loopback test, Line status test, Modem
control register test, Data transfer test (at baud rates from 300 BPS to 115.2KBPS and FIFO test.
Parallel Port
A maximum of three parallel ports (LPT1 through LPT3) are tested. The test parameter window asks the
user whether a printer or a loopback plug is connected. If these are not connected, only the register
read/write test is performed. Otherwise, the following tests are performed: Register test, IRQ activation test,
Pattern printing, Bold letter printing, Compressed mode printing, Printer form feed test, and ECP test.
Video Test
The Video Test Menu includes functional exercising of the video memory.
Video Memory Test
The Video Memory Test checks the base 256k of video memory for integrity by performing a memory
pattern test.
IDE CD-ROM
The IDE Tests include exercising of the CD-ROM tray response, data, and audio if present.
IDE CD Data Test
This test reads logical blocks from the CDROM. If the starting logical block number and end logical block
number fields are not specified, the test starts reading from block 0 and terminates at the last block of
CDROM. This test will fail if an audio CD is inserted inside the drive.
