I like debugging ...
Seems that the problem isn't related to the pxelinux.0 version but to
something related to menus etc.
Quite small "/tftpboot" directory, with only 1 program:
LABEL LINBO
KERNEL linbo
APPEND initrd=linbofs.gz acpi=off noapic nolapic irqpoll pci=routeirq pnpbios=off nomce vga=785 quiet
that works with full speed.
Big "/tftpboot" directory, with menus and submenus:
"default" with:
# klonen
LABEL Klonen
MENU LABEL ^Klonen
kernel menu.c32
append conf/clonen.conf zurueck.txt
with "conf/clonen.conf":
include conf/linbo.conf
with "conf/linbo.conf"
# linbo.conf
LABEL LINBO
MENU LABEL Linbo
KERNEL linbo/linbo
APPEND initrd=linbo/linbofs.gz acpi=off noapic nolapic irqpoll pci=routeirq pnpbios=off nomce vga=785 server=192.168.0.1
# one long APPEND line
runs awfully slow.
It's no problem only with this program, I've choosen it only because its
original PXE routine only needs "pxelinux.0".
And I have built this menu structure together with a newer pxelinux
version (something like 4.00).
Where flies the bug?
Viele Gruesse!
Helmut
