for those that actually care and so we can put the whole "900 screen on 70x" questions to rest....
some of you have been reading/posting about the whole larger screen issue so ignore this middle part if you're already "brushed up"...
for those that don't know/haven't heard there has been a L O N G time debate searching for the "holy grail" of 70x mods ever since the 900 series was announced about trying to get a 900's 8.9 inch LCD in a 70x... several (if not many) have tried this and sadly found that dispite the similarity in hardware and as i recently found strikingly similar firmware the 700 will run the 900 screen easily but "squish" the image into a 7" section leaving the rest of the screen black/unusable and no matter what was tried you just couldn't get it to strech out (this was all OS based of course)
then one day i decided to be a stuborn a$$ and start pondering and arguing at times the validity and possibility of how we could actually make this work...
long story short it came down to the bios limitations of the intel video chipset that both models share
basicly the bios tells the chipset what "size" the output image should be and to not go beyond that.
so without much further guilding the lilly i just slapped the video structure from the recent 900 bios (ver 906) into the recent 702 bios re-packed the stupid thing and here it is... i'm still waiting on my 900 screen to come in the mail (plus other goodies from a 900) but this is the first build i've gotten to run stable virtualized with AMIBCP (american megatrends production editor for AMI rom files)
702-ASUS-0500.rom - 0.50MB
for those like jkk and vinhtvu2 that tried in the early days and may still have the bits and bobs still lying about and want to try.
as usual with anything like this i can't take any legal responsibility for what may happen to your machine if you do this since it is OBVIOULY an un official bios build and asus wont support using and the certainly wont like you butchering up your screen...
short of it all is that if you use my bios and something goes wrong it's not my fault... i'm just warning you now... all should go well though
CHEERS

oh... i almost forgot... the originator of my bios inspiration is vinhtvu2 when he made mention of trying to flash the 900 bios rom into his 701 (unsuccessful)... just thought i should at least give a shout out
~~edit: and just for the record this is officially post # 486 for me... not that it means much to most but
that number always makes me smile and pine for simpler days

Nice work - however i dont have a 900 screen laying around so i cant test it... But if it works i would start planning that as a mod too

So this bios is from a 702? What about the 701?
Offline
well, the only real difference between the 701 and 702 when it comes to the bios is the IDE enumeration for the primary SSD... since the only real defference between them is really just on board ssd or mini pci-e ssd the bios should be fine for both 701 and 702 since no matter what it points to first it will still be able to find the SSD in one place or another... kinda like using "cable select" when installing drives in your desktop.
Offline
since i'm sure i'll get asked a million and twelve times i'll just tell everyone now...
as mentioned above that bios should be fine for 701 and 2 i just used the 502 bios as a base with bits from the 906 bios
B U T i am working on other versions. this is a rough beta version so to speak for those brave enough to test it. i just ran it on my 702 (without 8.9" upgrade) and it runs just fine making my veiwable screen extend off the factory 7" lcd (YAY!)
i'm going to put out some variants of the 0501/0511 and 402/404 bios' as well to see if they're a bit more accomidating for you 701 folks (501/511 mainly just to add 900mhz on boot up)
if anyone tries this first version out let me know what your experiences are PLEASE

I would love to try this and give my peregrin3 project a bigger screen... but i'd need to get a 8.9" screen and touchscreen for it and i already went on a spending spree. I'll let you know if I do decide to try it though.
on another note, would this bios work only for an 8.9" screen? what about anything bigger, say the 1000's 10" screen? would it be much of a change to tweak it for something larger? not that it'd be very feasible because finding any other larger lcd with the right connections would be hard..

Hey, while you have the BIOS open why not remove the silly PCI-e lock for the WiFi card? I can get Wifi/BT mini PCI-e cards from a manufacturer in Taiwan... that would give 700/900 series both with NO SOLDERING WHATSOEVER!
Offline
Alright, I guess you're waiting for me to reply and try this :-)
It'll have to wait as I'm on winter break and far away from my toys.... not to mention the 900 LCD is now coupled with a 901 motherboard inside a 5.25 CD drive tray inside my brother's car as a "carputer"....
I'll try it as soon as I get back though... cuz this is GREAT news and I would LOVE to have the ultimate 702 :-)

i've tried to get the oem lock off the mini pci-e slot but from what i can tell i'm going to have to rewrite the entire pci bus section and since the entire system uses it that's quite the chore... i'll put up my sourced versions for anybody to play with if you really want... i'm not sure about you guys but i used IDA 5-pro and AMIBCP to deconstruct and work with the rom but other bin and hex decomps should work... just let me know and i'll post up the source somewhere.
Offline
also it needs a better "build name" i just calle it "0500" so that it can be easily swapped out for the standard 0502 rom without running into that annoying not being able to downgrade thing since i'm too lazy to track it down and remove it right now (one rom at a time folks!)
Offline
so... i did a bit more poking around in the video "display manager" module (as asus has it labeled in the bios) and actually found that for some goofy reason there is AGP support?!?!?
is anyone else wierded out by this?
i know the bios roms are built on a standard AMI core 8 structure but why bother bloating the rom file leaving this in?
now i'm wondering what i can do with it... any ideas?

Am I dreaming? this is too good to be true!
This is the best possible upgrade for the 701, great work.....I am watching this thread with much interest. when do you expect to receive an 8.9" screen?
Offline
now i'm wondering what i can do with it... any ideas?
Emulating DX9 AGP Texture Acceleration somehow? I have games that should rightfully run on low spec hardware that phail because of this silly check...
Offline
@surfer due:
it is true but as noted above this bios is only a beta version to extend the display over the larger screen, while it runs stable under "emulated" it may still have it's faults. my screen should be here soon, hopefully i can have test shots and vids up after x-mas.
@ultimate chicken:
i think that would be more of a hardware thing, i can turn the feature on in the bios (presumably) but i'm not sure it will do much without hardware to reffer to.
Offline
beside the 900's lcd, what other parts are needed for the upgrade?
thanks in advance
thanks for putting in the long hours in your coding
Offline
basicly the screen from an original 900 is all that is needed parts wise, but ofcourse you'll need a usb stick or SD card to flash the bios. AFAIK it has to be an ORIGINAL 900 screen, the fit right into the same plug as the 70x screens, 901's and later models like the 900a/ha have a different connecter. i may be wrong on that bit though... but until i get some more testing done i wouldn't advise buying the new screen just for this. i don't want people hating me if something goes wrong and they wasted thier money

Randy is correct, a 900 screen and cable it the best way to go. The lcd cable from a 900 is crucial. The lcd itself is the same from a 900 to a 901, but without the proper cable it will not plug in.
I am still curious if the backlight is an issue like it was when I tried it. Mine never shut off.

the back light i'm still uncertain about, i'm brobably going to have to try a few different fixes for that when i get the chance, i think that will take some patching of the ACPI controls in the bios... since i don't have the whole unit yet it's just gunna have to wait 
soon as my fat drunken holiday stooper passes (some time in '09) i'll see what can be done about this... all truth is i posted this here to see if some one else wanted to work on the hardware bit and save me the trouble
nah, just kidding. it's more of an ADD thing... or as some call it, i'm a "sever multi-tasker" i just get too wrapped in one project to the next. but if i get this working maybe we'll have to get PvP to make us some screen bezels

in regards to the 900 cable:
this one:

or this one:

not bad for under 40 dollars shipped. the lcd goes for like 100 on ebay
Are you planing on relocating the speakers, or just removing them completely?
Offline
i'm probably just going to ditch my speakers and use my moto stereo bluetooth headset, i barely use the factory speakers as is but i might move them to the underside like the 900's anyway just in case.
as for the cable i'm not quite sure... it would be better if they had a picture 
Offline
Wow, I haven't checked these boards in ages, and decided to come check out if anyone's made progress on this exact mod.
Perfect timing? :p
My finger's on the trigger for a 900 LCD as soon as you tested the beta build and it works.
What exactly was the issue with the backlighting again? I haven't been here for a while, so I forgot.
EDIT:
1) Re: Your question in the other topic
- I would prefer to have the CPU boot up at 900MHz, and then over/down clock according to our needs with eeectl
2) I haven't played around with the BIOS for too long, so I forgot how to flash...
If you can give me a quick run-through, I can probably tell you whether it works on a 701 or not by tonight.

This was done a long time ago by modifying the video bios and flashing it. There were several threads about this and I gave the intel video bios flasher out to several people.
I would recommend this approach though as the video bios is a one shot deal and a mistake would cause you to have to flash in the dark... well I guess this is a one shot deal too. Still, I would use this method.

http://wiki.eeeuser.com/howto:updatebio … 20flashing
this is the wiki way of doing it but there are tons of other ways really, just give it a search, i prefer using afudos which can be found with instructions all over the place.
flexgrip:
the vbios method (afaik) was never really confirmed nor denied and much like you said this way seems easier/safer. i'm aware of lazetags work with the vbios in simpler re-writes to the driver but that's neither here nor there. i've heard far too many horor stories of 9xx series intel chipsets not liking to take vbios flashing.
but since the 900 and 70x run the same basic setup it just makes more sense (to me anyway) to change initial output in this manner

I'm just using Alt+F2 and a USB stick, got this error:
EZ-Flash starting BIOS update
Checking for USB device
USB Device found
Reading file "701.ROM". Completed.
Error! ROMID is not compatible with existing BIOS ROMID
Edit:
My current BIOS is 8804, with LazerTag's graphics driver (from ages ago)
This is also shown when I go into BIOS (my current one):
EC Firmware Version:701_065
