Appendix A: Reference information A-
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. There are two recommended
procedures for disabling the memory managers, depending on the operating
system you are using. One consists of pressing the key (only if you
are using MS-DOS 5.0 or above), and the other requires the creation of a
boot disk.
