bug on ARAR8132 ??

[ren22]

hi

i have an asus eee pc 1005ah with an Atheros Onboard LAN AR8132 rev.c0 ( Asustek 838a )


if i try to boot without any keystrokes while booting, to interrupt the boot process, from iPXE i got dhcp timeout and Error number 0x4c106035 "http://ipxe.org/err/4c106035"

if i try after the first dhcp request to interrupt with CTRL+B (on the first CTRL+B message prompt)
and enter follow commands it works ...
dhcp net0
dhcp XX:X:X:X:X: ..... OK
boot http://example.org/boot_script.php

if i try to load it automaticly as written in the configs i got dhcp timeout.
i am using the latest versions of all using software.
isc-dhcp-server was installed by apt as binary.

thanks
