The diagnostic tests are intended to test
only
IBM
products. Non-IBM products, prototype card, or modified
options can give false errors and invalid system responses.
Warning: The drives might have been rearranged or the
drive startup sequence might have been altered. Be
extremely careful during write operations such as copying,
saving, or formatting. Data or programs can be written
over if you select an incorrect drive.
Japanese Models Only
The Japanese model of the ThinkPad 700C has an
89-key keyboard. This keyboard is identified by the
additional keys at the left and right sides of the
spacebar.
When testing the diskette drive in the Japanese
model, the 1.2MB format (8 sectors per track and 15
sectors per track) in addition to the 720KB and
1.44MB formats are tested to ensure correct
operation.
A 2.0MB capacity diskette is required when testing the
1.2MB format.

2. Check all cables and power cords for correct
