The Stéphane ARQUER  hello.exe is reported by hpa to be working.

That did made me curious.

After getting a simular pxelinux.cfg as above, I did get

| Booting...
| Invalid ELF file or insufficient memory
| boot:

Due the succes report from HPA,
I knew there is something wrong with my setup.

After replacing pxelinux.0 with a newer one.
(in fact making a better match of 'elf.c32' and 'pxelinux.0' version wise )
is 'Booting...' immediate follow-up with a complete black screen
for about five seconds ( 900MHz Intel Pentium III ) and the text

| Initalized console on port CONSOLE
|
|
|
| *** HELLO WORLD TEST ***
| Hello World
| *** END OF HELLO WORLD TEST ***
|
| EXECUTIVE SHUTDOWN! Any key to reboot...

in a new screen. Hitting a key indeed reboots.


It was interresting to see 'elf.c32' working, especial the logging
in the TFTP server where the fetch of elf.c32 immediate was followed
with hello.exe.

Yes


Anyway, I hope this posting helps getting RTEMS development running for a
netbooting targetcomputer.
