iPXE discussion forum

Just thought I'd share:

Embedded code in iPXE:

Code:

#!ipxe

#Generic Boot Script

:retry

dhcp

chain http://%WEBSERVER_DNS_NAME%/ipxe/boot/${uuid}.ipxe || goto retry

In WebServer Directory:

%WEB_ROOT_DIRECTORY%/ipxe/boot/%UUID%.ipxe

Code:

#!ipxe

goto startme

:retry

sleep 5

:startme

set keep-san 1

set initiator-iqn %IQN_QUALIFIER:%CLIENT_DNS_NAME%

sanboot --drive 0x80 iscsi:%TARGET_DNS_NAME%::::%IQN_QUALIFIER%:%TARGET_NAME% ||

sanboot --drive 0x81 --no-describe http://%TARGET_DNS_NAME%/scientific_linux/6.1/x86_64/iso/SL-61-x86_64-2011-07-27-boot.iso || goto retry

This is working very well whilst I get my PHP environment working...

Quite ingenious, I'd say. I'd choose something else than Scientific Linux, but to each his own. Smile

SL isn't too bad... I'm an enterprise customer at work, so I gravitate towards RHEL, and SLES/SLED and derivatives.

I still hate the fact that you get a infinite loop by default when chainloading. And because i keep changing my mind for home usage (just fooling around with it's possibilities), i don't want to embed a new script every time. So i wrote this. Blush

#!ipxe
:retry_dhcp
dhcp || goto retry_dhcp
iseq ${filename} undionly.kpxe && set filename ${filename}.script
chain ${filename}

this way you can break the loop in the dhcp server as discribed in the manuals, and if you have a dhcp server that does not have this option the embeded script will break it for you. I would be nice if the dhcp+autoboot that is run when there is no embeded script would have something like this because the loop is just stupid. Sad
