- 2) I have added conditional code to main.c from Etherboot 5.0.4 to add
- a new default boot option and I have included the modified main.c as an
- attachment to this message.
-
- As I received Etherboot 5.0.4, in the Config file, if you select
- ASK_BOOT with a non zero time-out option, then you also get to set
- ANS_DEFAULT = ANS_NETWORK or ANS_DEFAULT = ANS_LOCAL to determine what
- will happen if the operator does not respond to the prompt. I have now
- added conditional code in main.c such that if you set ANS_DEFAULT =
- ANS_AUTO, the default answer will be set according to whether or not
- there is a hard disk in the system (as detected by the BIOS). If a hard
- disk is present, then if the operator does nothing, the system will boot
- from it. If a hard disk does not exist, then again if the operator does
- nothing, the system will boot via the network. Either way, for our
- particular environment, the operator has to do nothing to get it to boot
- correctly. Yet the operator can still override the default selection
- to, for example, allow a unit without a hard disk, to boot directly from
- a floppy rather than the network, or to allow a unit with a hard disk,
- to boot from the network.
-
- I don
- production version of Etherboot, but I thought I
- let you get it into the system if you feel it might be appropriate.

- [Ed: On a compliant BIOS, it will actually boot the next device in the
- BIOS list if local is selected, either explicitly or by timeout, which
- may or may not be the hard disk, which is why it
- not included in the distribution by default.]
