Subject: [dhcp] Assume PXE options are in DHCPOFFER only if boot menu is included
|
|
X-Git-Url: http://git.etherboot.org/?p=gpxe.git;a=commitdiff_plain;h=734061e9c60103439e13d72c68e50ee362f3ba91

[dhcp] Assume PXE options are in DHCPOFFER only if boot menu is included
|
|
|
|
IBM's Tivoli Provisioning Manager for OS Deployment, when acting as a
|
|
ProxyDHCP server, sends an initial offer with a vendor class of "PXEClient"
|
|
and vendor-encapsulated options that have nothing to do with PXE. To
|
|
differentiate between this case and the case of a ProxyDHCP server that
|
|
sends all PXE options in its initial offer, modify gPXE to check for
|
|
the presence of an encapsulated PXE boot menu option (43.9) instead of
|
|
simply checking for the existence of any encapsulated options at all.
|
|
This is the same check used by the Intel vendor PXE ROM.
