Etherboot from Award BIOS 4.51

Hi.

Reffering to:

I would like to know, if you really checked the vendor and device id of your
network card and if you choosed the correct/suitable etherboot image.


After downloading:
http://motherboards.mbarron.net/models/pcchips/m520.htm
-->
ftp://User:[email protected]/manuals/pcchips/m520.zip

...I extracted: "520_Bios_19971016S_AWD.zip" --> "5201016s.bin" and checked
it with CBROM:


CBROM220.EXE 5201016s.bin /d

a)
original.tmp is the main/system BIOS binary including BIOS setup menu.

b)
NCR307.16K is a SCSI controller BIOS extension.
"NCR SDMS (TM) V3.0 PCI SCSI BIOS, PCI Rev. 2.0"

c)
765.rom is a VGA BIOS for a S3 graphics card with the
+ vendor id:5333
+ device id: 8811


It is really curios that NCR307.16K has a header without (a) "PCIR"
string(s).
"PCIR" can just be found at the end of the file.

Reffering to maman's "Low Cost Embedded x86 Teaching
Tool"

... the PCIR string should be at the beginning of a PCI extension ROM

However, try to add the correct/suitable etherboot rom
(with suitable Vendor/DeviceID) to your Award BIOS as PCI rom again.

Also try different CBROM versions (1.xx, 2.xx)



Furthermore you can try to add the etherboot PCI extension ROM as an ISA
extension ROM module.


Another possibility is to convert/re-build/re-compile the etherboot PCI
extension ROM to an ISA extension ROM module
(= an extension BIOS/ROM without PCI extension ROM/BIOS header).

After this, it should bo no problem to add an etherboot ISA extension
ROM/BIOS as an ISA BIOS module to the Award BIOS.


The huge advantage of an ISA rom is that it will be loaded by an
Award/Phoenix BIOS in any case.
