AW: [Oberon] Booters for ETH-Oberon ?

[Stauber Sven Philipp]

The assembler source code of the Oberon boot loader, MBR and Boot Manager are contained in the AosBuild.zip package (http://www.bluebottle.ethz.ch/downloads/crazy/AosBuild.zip). If you run AOS (or Oberon in AOS), you can use the stand-alone assembler PCAAMD64.Mod to assemble the code.
 
Best regards,
Sven Stauber

Have you seen these ?
Where can I get them ?

Yes I had read your CF installation, but I was so overwhelmed by the
amount of mechanical-engineering that you had to do to fit it that I
didn't realise that you actually booted from the CF.

Bootloaders are complex/problematic:
*  you often need to work at asm-level.
   N-O's Decoder.Mod is not perfect & was removed from the packages ?
* there are possiblilities of inconsistencies at several stages:
     the IDE's C,H,S,  the BIOS, lilo/Grub..etc. M$loth wants to kill any
     co-resident foreigners ...etc.

I've only ever had one ETH-Oberon that didn't need a fd0 to boot.

I'm also interested in soid-state-disks in connection with the OLPC
[one laptop per child] project, which I've been following.
My initial criticism seems flawed since even if the x86 CPU uses much
more power than an ARM, the 0.8Watts used is a small part of the
power needed by *any* significant LCD-display. And the OLPC has
got a specially power-economic display.

The OLPC takes 2 minutes to boot linux.
How long does your CF take to boot ETH-Oberon ?
I guess ETH-Oberon would not shine on the OLPC because OLPC is
not conveniently mouse-chordable -- AFIAK ?

I'm including the extract below from OLPC, because it's the first
confirmation of a principle which is central to me, that I've seen:
identifying entities by their 'recentcy' is more usefull than eg.
alphabetically by name [and is handled nicely by mc, which I
mentioned].
That's why stacks are usefull.
Perhaps different users have different thinking methods ?
Evidently many people prefer to search alphabetically for
ThatFunnyNamed873File than 'the one I used yesterday' ?
