part of the boot process; any other programs that were loaded before the cold
boot will not be reloaded automatically.
Safe Boot
During the DOS boot sequence, control is passed sequentially to the
config.sys
files on drives
A
,
B
, and
C
. A similar process is followed for the
autoexec.bat
files on each drive. (See chapter 5 for information about the
Falcon’s drives and system files.)
It is possible for a driver or application loading from the
config.sys
or
autoexec.bat
file on drive
C
to hang the system. A cold or warm boot of
the unit will not directly correct the problem, because the troublesome
program will be started again as part of the boot sequence. What is required is a
method by which the
config.sys
or
autoexec.bat
file on drive
C
and
the loading of the
cfgdev.sys
and
decode.sys
drivers can be taken out
of the normal boot sequence. DOS can help some, with the
<CTL>+<C>
, and
<F8>
escape sequences.
Table 7-3: Falcon Safe Boot Key Sequences
The unit indicates safe-boot mode by emitting a low tone followed by a higher-
pitched tone. The flash drive (
C
) and the RAM drive (
D
) will be preserved, and
the boot sequence will place the unit at the
C:\>
prompt.
