[Qemu-devel] [PATCH] EtherBoot and RTEMS works on QEMU

Hello

The following patch adds EtherBoot and RTEMS to QEMU OS Support web
page.

I am very impressed with QEMU. EtherBoot 3.5.9 and RTEMS 4.6.2 worked
out of the box with network support using ISA-only system (-isa).

The EtherBoot rom was simply made by "make bin/ne.zlilo" and loading
that from a disc image with grub installed. I could not get EtherBoot
to work in PCI mode.

RTEMS 4.6.2 worked by compiling an application for the pc386 target with
an NE2000 NIC on port 0x300 and IRQ 9. This was tested by loading RTEMS
from a disk image with grub and by loading RTEMS using EtherBoot.

I know EtherBoot is not an OS, but I thinks it is important enough
application and should be added to the list anyway.

Please apply.

Regards
Lars Munch

Can you give me more information about the PCI problems ? Is NE2000 PCI 
supported by Etherboot in PCI mode ?

Looking through the EtherBoot NE2000 driver it appears to be ISA only.
Investigating the driver at bit futher I found that the NS8390 driver
works for PCI mode (build it by 'make bin/ns8390.zlilo'). So now it is
allready time to change the comments againg :-)

"Works with ne.zlilo rom on ISA-only system and ns8390.zlilo on PCI
systems."
