IPXE Version

[ymolinet]

ok.
I see that IPXE options contain ipxe.version, so I can do a test on this option to determine the current version of the IPXE ROM.
But IPXE Version string is like "1.0.0+ (ca319)" so I could not determine if this version is older than "1.0.0+ (6d72b4)". I could only determine if string are not equal (not like a simple number : upper or greater)

In my project, Debian 7.10 netboot failed during boot with an old IPXE ROM, but not with the "on-line" version (http://boot.ipxe.org/undionly.kpxe) it's working as fine. So my goal is to determine if the IPXE Rom is not so older to boot some OS.
