You still might be interested in the etherboot.m4 file from jumpwire; it provides a nice, easy way to generate ANSI sequences and DHCP option files (that can be loaded via TFTP using the extensions-path option). > >Dual-Head Range > >We understand that some schools do not have excessively large budgets for computers, whilst at the same >time needing to meet the > National Curriculum requirements to teach children computing.

For a long time, we had it marked as "under development" on the site and no-one expressed an interest. Even now that it is not explicitly marked as "under development", we still haven't had anyone actually wanting to buy one. When they do, we'll get it working. :-) For our uses, we only need dual X; it doesn't matter if only one of the "heads" can be used outside of X since our customers will never use them in this way.

I should also add that I don't intend to develop this version of the external menu program very far. I will just make it resemble the internal menuing as far as possible and then any improvements are up to you hackers. My goal here is to remove crud from Etherboot. The external program chaining mechanism is general and has been in Etherboot for over a year. It's documented in the developers guide and there are comments in the sample program. So you could start from scratch and create any fancy program you like. Lots of possibilities, use the mouse for input, animation, fractals, etc. etc. |

Ken, shure, i didn`t expect that YOU would do so. But for me, it will be VERY difficult to do because I have not very good experience in programming - so why not ask for that feature, make people "think" about and perhaps find someone with better skills who says: mhh, bootlogo? wait a minute.... :) regards Roland PS: gonna search for some demoscene-guys, they will go laughing and make an mindblowing 3d boot-menu for us...... ;) You really should give ftp://ftp.jp.scene.org/pub/demos/demos/1997/s/snc_omni.zip a try.

One thing I would like to do in conjunction with this is to figure out what we need to do to relocate etherboot. Allowing arbitrary to be down loaded. If you don't have to support callbacks this is trivial, with callbacks this becomes a more interesting challenge. Mostly I think etherboot can be moved to the highest available address below 4G, with just a touch of care. The challenges are keeping the overhead down, and still allowing dos BIOS calls. Because that needs a small chunk below 1MB. Eric |

Which is almost a callback, but it easier to deal with. The PXEEMU case definitely requires callbacks :( How is the boot filename specified? > >Mostly I think etherboot can be moved to the highest available address > >below 4G, with just a touch of care.

But I keep looking for something a little easier to code up. Eric |
