[Etherboot-developers] patch to fix tagged NBIs on Etherboot 5.1.2

[Miles N. <ca...@Iv...>]

You may already be aware of this, but I needed the following four-line
patch to make the development version 5.1.2 posted on Sourceforge work
with my mknbi-1.2 mknbi-dos image.

Thanks for your work on Etherboot.  It's much, much less crappy than I
remember it being five years ago.  Take care.

This has been fixed in the CVS, but Eric you'll find another error in
main.c in loadkernel() when -DDOWNLOAD_PROTO_NFS is defined.

announce on Freshmeat. I'll be busy for the next 3 days or so. This

One thing that absolutely must be done is to put a readme just before
download explaining that existing images must be rebuilt with
mknbi-1.2-10 or later (or to use the latest LTSP images, which I believe
are recent enough), otherwise we'll get this flood of why doesn't it
work with this image I've had since 1972? :-)

Feel free to work on that if you like.  I'm actually a little less busy 
than I was, and can help.  If you'd like to take the opportunity to 
play with PHP, by all means go ahead.  I guess I should download the 
release and take a peek...

Alright, I just downloaded rc8 and did:

    diff -u ~/etherboot-5.1.2rc8/src/Config ~/etherboot-5.0.7/src/Config

and

    diff -u ~/etherboot-5.1.2rc8/src/NIC ~/etherboot-5.0.7/src/NIC

Nice work Eric.  I hope to be of some help with drivers soon.

It looks as though the changes to the rom-o-matic code won't be too 
hard.  Mostly new parameters.  NIC hasn't changed format, so that won't 
be a problem.  The ide and floppy entries at the bottom of NIC look 
interesting;  I'll have to see what magic is going on there.

It's nice to be able to sit on a cold Sunday evening in Cambridge and 
look at some nice code for a change.  Maybe I can help with driver 
conversion for multicast support.

Anyway, great work, folks.  What sorts of things could you use some 
help on?

I think so, if the FreeBSD compile fixes are in.

At this point if there are problems with relocation, or with
multicast we can fairly certainly say that it is the driver.

It is definitely time to stabalizing what we have or we
may never get to 5.2.x.

And what we need now are bug reports.  And without
at least a development release I doubt we will get them.

Try that in units of sectors.  If you are not careful some versions
of fdisk will cylinder align your partitions, and will start your
first partition at 63 sectors.  Which is a little to far on the disk.
You should be able to force it though using units of sectors.

[Etherboot-developers] RE: Bug in etherboot 5.1.2rc7

[<hc...@et...>]

Strange.. 

I tried to put kernel.elf on the first partition but it failed. 
I organized my 1G hdd as follows. 

Disk /dev/hda: 16 heads, 63 sectors, 2100 cylinders
Units = cylinders of 1008 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1             1         3      1480+  83  Linux
/dev/hda2             4      2100   1056888   83  Linux   

In the hda1 I placed kernel.elf with dd if=kernel.elf of=/dev/hda1 and
placed rootfs on hda2
But It fails to find elf image. 
What did I wrong? 
I make kernel.elf with mkelfImage version 1.16.

As long as the ELF header is within the first 8K of the disk it will
work.  So just make certain your first partition starts at sector 1,
and is big enough to hold your boot elf image, and you can use
the disk for multiple things.

Thank you.

I think we ought to test it out if the problem exists. It=20
depends on which part of the 640K DOS uses and which part=20

Hello from Gregg C Levine
Hmm. Since I'll be around this year, as always, I should think we should
demo the usual things, and include having either the client, or server,
booting from Linux BIOS. And if you want to, I'll even contribute some of my
copious free time, for this years, sessions. I'm kidding about that comment,
about time. I meant, "free time", for this coming year's LinuxWorld NY 2003,
I will be glad to contribute some time. All you would need to do, Marty, is
to show me, what to do, and I'll do it. It will save you to make EPROMS, and
to answer questions. Those that you can't answer, I will, if I can. We
should get the Linux BIOS folks involved in this one.

[Etherboot-developers] LinuxWorld NY 2003

[Marty C. <ma...@et...>]

Hello Everyone,

The Etherboot Project will be exhibiting at the LinuxWorld Conference &
Expo in New York, January 22- 24, 2003!  You can check out show
information at http://www.linuxworldexpo.com/

This will be our 5th show in a row, and they get better every time!  I
hope that lots of folks can come, and we can certainly use some help in
the booth.  We will be in .ORG booth #5.

LinuxWorld Expos are a great time to meet and greet fellow Free and Open
Software community members, and there are always interesting new products
and ideas.

We'll be sending reminders as the time grows nearer, but we just got our
confirmation the other day, and wanted to give you an early "heads up". 
Let us know if you plan to come soon (Ken.. Markus.. Eric.. Michael..
Don... etc... ;)  There's a nice big dinner for anyone who can make it.

So, what cool things should we demo this time around? ;)

Marty

Re: [Etherboot-developers] Help on Booting WinME DOS

In former DOS versions, there was a switch to himem.sys called /testmem:off.
IIRC, himem.sys is loaded automagically always _after_ config.sys if it had
not been specified. I have no mileage on WinME, but I believe on Win98 you
could simply enter
DEVICE=C:\windows\himem.sys /testmem:off
and it did exactly this.
This way you could avoid your RAM  be "checked", which should preserve the
ramdisk.

Possible in theory.  The problem I see is that MS-DOS uses the Lowmem area
without asking, so it could load e.g. command.com right there and you couldn't
even say "zap" before your virtual disk is nuked.

If you like, read the documentation about the NBI format, shipped along with
etherboot.

[Etherboot-developers] Help on Booting WinME DOS

[<kf1...@hk...>]

Hi,

I experience problem of booting WinME DOS as its IO.SYS 
loading HIMEM.SYS automatically. This conflicts with the 
initial ramdisk installed at or above 1M in High Memory 
Area.

I need to run dos programs in WinME DOS and I can put all 
my programs and WinME DOS on a 360K floppy.

If we could install the initial ramdisk in Low Memory Area, 
may be we can withstand the automatic testing of High 
Memory Area by the HIMEM.SYS loaded up by IO.SYS.

So is it possible to install the initial ramdisk in the 
first 640K of the Low Memory Area?

Thanks for anybody's enlightenment.

Best regards,
Johnson CHEN
