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. + +Thanks, + +Steve Tilden +Sicom Systems Inc. +stilden@sicom-sys.com + +[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.] |
