A.3 PHLASH16.EXE and memory managers
Phlash16 may fail if your system is using memory managers, in which case the
utility will display the following message:
Memory manager error message
If you see this message after you execute Phlash16, you must disable the
memory manager on your system. Follow the instructions in the Disabling memory
managers section in this chapter.
Because Phlash16.EXE may require the use of extended memory, it will not run
if it detects the presence of an extended-memory manager such as HIMEM.SYS,
EMM386, or QEMM. To avoid conflict with disk caching programs, the program
checks for VCPI, DPMI and XMS.
The program does not check for VDISK because MS-DOS 5 and later versions
do not support that server.
If the program detects any of these utilities, the program reports a failure and
terminates.
Disabling memory managers
To avoid failure when flashing, you must disable the memory managers that load
from CONFIG.SYS and AUTOEXEC.BAT.
To disable the memory managers:
1. Boot from a bootable floppy disk created from MS-DOS 6.22.
2. During the boot process, when the message "Press any key to continue" is
displayed, press <F5>.
3. The message "MS-DOS is bypassing CONFIG.SYS and AUTOEXEC.BAT
file" appears. The memory managers will then be disabled. Do not interrupt
the process.
4. When done, flash the BIOS according to instructions in section "4.1.2
Updating the Phoenix Phlash16 Utility.

Cannot flash if Memory Managers (e.g. EMM386) present
