SECTION 3 PROGRAM FOR SERVICE
3-1. General
The Diagnostic Programs for Service are available with the following three kinds. DISKETTE TEST FDD is tested. As the read/write operation is performed to the floppy disk, set the DOS formatted 1.44M disk without the write protection before the PC-Doctor is started. Also, if the PC-Doctor is booted from the CD, the boot image of CD is treated as the floppy 0 (drive A), and accordingly the FDD is treated as the floppy 1 (drive B). In this case, the floppy 0 cannot be tested and N/A is displayed as the test result, but this is not a fault. MISCELLANEOUS TEST Other devices are tested. CD/DVD-ROM read check, CPU type check, and configuration check of PCI device, etc. are executed.

1. PC-Doctor

2. Sis Video Diag
This can test the VGA (sis 650/740 chipset built in).

3. nVIDIA Video Diag
