Hello everyone.

 

My issue is that I purchased a nice expensive video card for my last computer.  An nvidia Quattro 4000.  My computer had some issue, so I simply bought a new one.  (Was planning on building one, with my bro-in-law's help, but decided to just get one.)  It was an ASUS essentio, i7, with windows 8 64-bit.

 

I checked it out to make sure there weren't any issues, then moved a power supply, and hard drive to my new system.  But I also tried to move the video card.  It didn't work, so I took it out, and through research, and phone calls, found out that my video card will not work with UEFI bios.  I found that other ASUS systems have a legacy option, but when I get into the bios, it is not there.

 

I even contacted ASUS, and assume I contacted the wrong person.  I felt like I was chewed out for opening my system, and after a few emails back and forth was informed there wasn't a legacy bios, and they weren't going to help me.

 

I was supremely annoyed about all of this, when I have ASUS on my facebook, and I keep receiving videos about all these upgrades, and mod systems from them.  (Sorry, ranting.)

 

Anyway, does anyone know how to get a legacy bios for my system, or where it may be hiding?  I really would prefer to use this video card, especially since it cost more then the computer I "upgraded" to.

 

Thanks for any assistance.

Sorry to hear about your troubles, and a look at the ASUS spec for your computer shows that the Win 8 and Win 7 varieties use different chipsets so it isn't just a simple matter of looking for a set of Win 7 drivers for your BIOS / UEFI. However, i did find this thread on BC, which while a bit long and rambling if you stick in - ie towards the end of it - there are a couple of suggestions which may give you some help.

I've had of this nasty before... here's a fix

 

http://www.pcmag.com/article2/0,2817,2417361,00.asp

 

It's not quite what your trying to do, but the uefi disable is in there....

 

edit: yes, ASUS are weak service. I don't buy their machines anymore.

 

edit edit: I don't know how well win 8 will work in legacy bios, I have to say I am completely ignorant of this (windows 8 that is) and it may pay to do some investigation and research before hacking it.

 

edit edit edit: damn you Microsoft! moved the bloody goal posts again!

Should have posted earlier.  Followed the pcmag article, and was amazed that it was a roundabout way to get to the bios that I could have simply booted up, and hit f2.  Problem is, I have already been all over this, and there is no legacy bios link.

 

The only thing I could find in the link to the other thread here was another link that took me through the same things as the pcmag article.  Other then that I can't figure out how it could help.

 

But the statement that I need a windows 7 bios installed, that is kind of what I was asking.  How do I get a legacy bios installed if this computer doesn't have it, which as far as I know it doesn't?

 

Thanks everyone for trying to help.

I'll ask a friend of mine who has done a few retro-grades... apparently you cannot change the bios to legacy in the bios boot screen he says, but only in Windows. (or make it available to be changed on boot, or something equally as stupid) I won't see him again till Monday to ask him more specific details though.

 

Maybe someone else can fill this blank meanwhile?

There is a way to disable UEFI as well, but doing so will render the Windows 8 system unbootable, as there is no MBR on the disk(s) (UEFI uses/requires GPT). If you're going to be doing this I would advise to switch to Windows 7, and then try the legacy option.

The BIOS is in the motherboard, so getting a different motherboard will fix this issue, if you want to go that route...
