[syslinux] Syslinux Digest, Vol 116, Issue 20

[Torgeir.Wulfsberg at kongsberg.com]

Hi!

We use Windows tftp-servers (so I dont think switching now would be an alternative). But I can try to suggest it.

More specific, vendor id of the mac address, is what I want to be able to "choose" (if match) which bootmenu to display.

Like all broadcom NICs we have would boot the undionly.kpxe "menu!! (I am having some trouble with broadcom (PCI fiber) and iPXE :)
And the rest would use ipxe.pxe (works best for our setup).

Would it be much work to implement or rather have available as an patch, so if anyone else are in need of this later, we could just patch the code and compile ourself.

Torgeir

Not really very useful; besides the rather obvious ambiguity, there
simply isn't a lot of locality in MAC space.

There *may* be some value in specifically the OID portion of the MAC
address (the 01 for Ethernet plus three octets), but I have yet to hear
a compelling enough use case for everyone else to take the load time
penalty.
