ERROR: Cannot write into high mem

[macovey@aport.ru]

Greetings,

The task is re-use our old PCs and make terminals out of them.
I've configured software suite including DHCPd, tftpd and
netboot-0.8.1 (under Red Hat 7.0) for booting diskless clients.
Everything work just fine on the server side.

So the problem is on client side, as I suppose.

Here I have wrote down the messages on the clients display:
......(Decompressing boot image)
......(Info about packet driver)
Boot-Rom V0.8.1, Copyright (C) 1995-1998 G. Kuhlmann

Block 8 Image 2: Start=10400, End=20000
Block 137 ERROR: Cannot write into high mem
Insert boot disk and press a key

----------------
Configuration of the client:

PC/AT 80286
ROM-BIOS date 05/05/91
Base Memory 640 KB
Ext. memory 128 KB
no HDD
NE2000 compatible NIC
----------------

The DOS-boot-image was made of msdos.sys, io.sys and command.com with
mknbi-dos utility.

If anyone knows how can I work it out, tell me, please.
Any advice will be appreciated.

Many thanks,
