In addition to ALT-F2 (which displays processing of CONFIG.SYS statements), ALF-F1 can be used to perform a number of alternate boot sequences. These are shown below. The display can also be customized if you wish to add your own choices. Note that if archives have been performed, they will also be listed. Also note that this mechanism is slightly different from Warp V3 in which character keys (C, V, etc) were used to make choices.
Other notes related to using the FX keys when the white OS/2 block is displayed during boot:
RECOVERY CHOICES
Select the system configuration file to be used, or enter the option
corresponding to the archive desired.
ESC - Continue the boot process using \CONFIG.SYS without changes
F2 - Go to command line, (no files replaced, use original CONFIG.SYS)
F3 - Reset primary video display to VGA and reboot
F4 - Restart the system from the Maintenance Desktop (Selective Install)
F5 - Enable full hardware detection
F6 - Disable hardware detection
Choosing an archive from the list below replaces your current CONFIG.SYS,
Desktop directory, and INI files with older versions. These older versions
might be different from your current files. Your current files are saved in
\OS2\ARCHIVES\CURRENT.
