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't know it the code I have added might be correct for a future
|
||
|
|
production version of Etherboot, but I thought I'd send it to you and
|
||
|
|
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's less than general and
|
||
|
|
not included in the distribution by default.]
