The following error message is prompted when entering GHOST through PXE network startup or USB flash drive startup using Chenglong Web Service or other network software:

ERROR:Unable to control A20 line!XMS Driver not installed.

Warning:the high memory area (HMA) is not available.

Additional low memory (below 640K) will be used instead.

The reason for this error is that the CPU of some new machines cannot be recognized by the CPU (A20) address, and the high memory cannot be used. UMBPCI.SYS and high memory himem.sys are the memory programs called by most network software nowadays, but this UMBPCI and HIMEM cannot be used on these A20 error machines.

Solution:

Just replace the startup file.

Open Chenglong Web maintenance, select image restore, jump out of the DHCP software after receiving the client, copy the DHCP directory, and replace the startup files after entering the directory.-HD is a full restore, and-C is a C disk restore.

After the change, you can reselect the mirror.

Note: every time you close the software, reopening the software requires replacing the file.
