[syslinux] ipappend and dos

[Aaron McSorley]

I'm using ipappend and getargs.com with a dos boot image to
get the environment variables for the IP and MAC. The format
of the %ip% environment variable is
  ip=<client-ip>:<boot-server-ip>:<gw-ip>:<netmask>
Is there a way to tell ipappend to assign these to individual arguments.
Or does anyone know a good way to parse each of these to individual variables in dos.
What I want to get is
  clientip=
  bootserver=
  gw=
  netmask=

And for the MAC the format is something like
  BOOTIF=00-00-00-00-00...
Anyone know how to strip out the dashes.

Thanks
