This is AFAIK the most widely used method for CD boot. Do other CDs work for
you?
Yes, all of my boot CDs work :-)
Meantime, I found the problem: cdboot.img was > 512 bytes. I forgot to
add the ld script necessary for the Cygwin build (-N does not work).
Should have checked this first, sorry.
Now the CD boots, but the result is interesting:
Real PC: escape to rescue mode, root=hd31, no (cd0) device, no modules.
VMWare: same.
VirtualPC: escape to rescue mode, root=cd15, (cd0) exists, normal mode
can be started manually.
VirtualBox: Works as expected.
Both floppy and "floppy(on)cd" both work as expected.
If this is a bug, I think it's better to fix it instead of adding workarounds.
Yes, but the patch provides the end-user with a simple way to create a
fall back boot CD when the normal boot CD does not work for whatever
reason. And the patch does not break anything existing.
