Warning" during BIOS initialization, highlight "Change is Expected,"
and press ENTER to continue.
v If you are reloading the hard drive because of reasons 4 or 5, then select
F5 to reload only the C: and D: partitions of the hard disk.
v If you have replaced the hard drive because of reasons 1 - 3, then select F8
to delete all hard disk partitions and restore the disk drive to the original
manufacturing data (or a newer version, if the CD is at a higher EC level).
The hard disk restore will take approximately five minutes.

the newly restored hard drive.

"Customer Configuration Save" diskette into drive A: that you created earlier in
this procedure.
12. Insert the diskette and follow the instructions on the screen to restore the
customer's configuration data.
13. Shutdown and reboot OS/2 to make this configuration take effect.
To replace an ESCON adapter:
1. Ensure that the 2074 is Offline to all operating systems and is available for
service. Shutdown OS/2 (Ctrl-Alt-Del) on the 2074. Label and disconnect all
external cables and power cords.
2. If the 2074 is mounted in a rack, then release the left and right side latches
and pull the 2074 out of the rack enclosure until both slide rails lock.
Note: When the 2074 is in the locked position, you can reach the cables on
the back of the 2074.
3. Slide the cover-release latch, located on the front panel, to the open position.
Then slide the top cover (rack mounted) or left side cover (tower configuration)
toward the rear of the 2074 about 25 mm (1 inch). Lift the cover off the 2074
and set the cover aside.
Attention: For proper cooling and airflow, replace the cover before turning
on the 2074. Operating the 2074 for extended periods of time (over 30
minutes) with the cover removed might damage 2074 components.
