Title: Option ROM seems to have no effect. Asus Pundit-S
Post by: cb12 on June 06, 2011, 19:45:59 PM
Hi, I have a little bit of a problem creating a Award BIOS ROM for my asus pundit-s with onboard nic.
Plop doesn't seem to be hooked by the bios, regardless of the bios boot options I use.

This is the way i created the rom:
0. Downloaded plpbt-5.0.12.zip
1. Creating the rom.
Code: [Select]
plpbtrom -vendorid 0x14E4 -deviceid 0x4401 -INT18 plpbtrom.bin plpbt.rom
INT18  - is used because the bios explicitly states "Boot Other: Network (INT18h)"
But I also tried without.

2. I continue with acbrom and release my vga rom and epa logo. (Seems to work fine without)
3. inserting the rom:
Code: [Select]
acbdrom /NET plpbt.rom
4. Then I flash the file via aflash.
5. Reboot, System comes up, without plop :(

Some questions I have:
How can I determine what is happening?
How does a PCI device place its boot rom in C0000h-EFFFFh? (according to BIOSBootSpecs)
How can I determine which space in C0000-EFFFF is not used?

Hello,

After having flashed your enhanced BIOS, have you been thinking about switching the boot device order, in the Award BIOS setup ?

I guess that once you inserted the Plop option rom in place of the genuine boot-from-the-network module, nothing may happen until you would actually instruct the BIOS... to boot from the "network" (i.e. to chain to the Plop rom).


I know that the thread is old, but I would be interested to share observations and results with you, as a P4S8L motherboard owner. I try to install the Plop option rom to the same Bios as yours. The goal here is to give USB booting capability to the machine and make of it a very nice platform for Lakka retro-gaming (https://github.com/libretro/Lakka-LibreELEC/issues/438#issuecomment-410347298) distribution.


Hope to see you online in the future.

Coming back to your thread after a few readings (among others the BIOS Boot Specification (http://www.scs.stanford.edu/05au-cs240c/lab/specsbbs101.pdf), see attachment :) I see two issues:



More investigation is needed.
