[ipxe-devel] iPXE looping when gPXE does not

[James A. Peltier]

Didn't work.  There must be something else going on here.

| | Are you sure you want "autoboot" in here? The script should never
| | continue
| | beyond this point, in either gPXE or iPXE, since autoboot will
| | either
| | fail or
| | never return.
| |
| | I assume you're trying to acquire an address via DHCP, in which case
| | maybe
| | something like:
| |
| | #!ipxe
| | echo "Hi There! We will be booting from http://mirror.its.sfu.ca/
| | today."
| | echo "It is assumed that you have dhcp networking."
| | dhcp
| | set 209:string pxelinux.cfg/default
| | set 210:string http://mirror.its.sfu.ca/tftpboot/
| | echo "Here we go!"
| | chain http://mirror.its.sfu.ca/tftpboot/pxelinux.0
| |
| | might work for you?
| |
| | Also, with iPXE you could look into making the script more robust by
| | handling
| | DHCP errors etc. For example:
| |
| | #!ipxe
| | echo "Hi There! We will be booting from http://mirror.its.sfu.ca/
| | today."
| | echo "It is assumed that you have dhcp networking."
| | :retry
| | dhcp || goto retry
| | set 209:string pxelinux.cfg/default
| | set 210:string http://mirror.its.sfu.ca/tftpboot/
| | echo "Here we go!"
| | chain http://mirror.its.sfu.ca/tftpboot/pxelinux.0 || goto retry
| |
| | which would cause both DHCP and the HTTP download to be retried
| | indefinitely if
| | e.g. the server were to be temporarily offline.
