[ipxe-devel] iPXE server

Adding the list back in to my reply.  Generally on mailing lists like this
one, Reply All is a good practice ;)

Hello Marcel,

The error you're getting is coming from the first line in your script:

> cpuid --ext 29 && set arch x86

Your script as written doesn't actually make use of the ${arch} variable,
so you could delete the line, comment it out, or add two pipe characters to
the end of the line to tell iPXE to ignore the error and continue executing
the script.

Commented, it would look like this:

> #cpuid --ext 29 && set arch x86

With the pipe operators (to ignore the error), it would look like this:

> cpuid --ext 29 && set arch x86 ||

And finally, with the line deleted, your entire script should look like:

> #!ipxe
> kernel http://192.168.1.254/win7DVD/wimboot
> initrd http://192.168.1.254/win7DVD/bootmgr             bootmgr
> initrd http://192.168.1.254/win7DVD/boot/bcd            BCD
> initrd http://192.168.1.254/win7DVD/boot/boot.sdi       boot.sdi
> initrd http://192.168.1.254/win7DVD/sources/boot.wim    boot.wim
> imgstat
> boot

For more general info on how iPXE scripting works, take a look at the
online documentation here: http://ipxe.org/scripting
Good luck, and best regards,
Andrew
