[request] Asus k55v Bios "hot-plug"/ "hot-swap" unlock

Hello guys
im new to this forum.
Im sorry if i posted in the wrong section :expressionless:
my story in a nutshell is that i bought “GDC V8 Mini pci-e” and a 1050 Ti graphics card
i connected it instead of the wireless slot in my laptop

when i login to windows it shows me that there is a 1050 card, but it says windows stopped it code 43
i searched online and they told me that i need to “Mod my bios” to enable "Advanced tab " “Hot-plug” option

So please could anyone help me ?
this is really my last hope Sad

This is my bios read from "Bios backup toolkit"
https://www.dropbox.com/s/uzu3d4q3zkarg9…VD.411.rom?dl=0

and this is the original rom from the asus website ( i dont know if this helps ):

Thanks alot


You probably mean the Hot Plug option in Chipset - PCH-IO Configuration - PCI Express Configuration

Unlocked Chipset tab.

Yes, thats what i need thanks alot.

i flashed it and it succeeded, but i cant find the Chipset tab :\ … do i have to do something else to unlock it?

thanks alot

@Ferrous ,i’m little bit off topic here but by any chance you know a way to unlock the CPU multiplier as well as the DRAM options in similar ASUS laptop bios?


How did you flash the modified bios?

@dani_tx
It’s impossible to unlock the multiplier of a non-K CPU.


How did you flash the modified bios?




Using AFUDOS.exe and Rufus to make the usb bootable
did i do something wrong :frowning: ?

What parameter(s) did you use with AFUDOS?
Only the Main Block is modified, so it should be Afudos filename /p

Aha, i see.
i wrote "afudos bios.rom /GAN"
i will try /p now and tell u what happens

Now when i try /p i get this error:

"Reading flash … done
FFS checksums … ok
Erasing Main Block … 0x00000000 (0%)
3 - Error : Problem erasing flash"

It seems that your BIOS is somehow write-protected.
Try Intel Flash Programming Tool v8 instead.
fpt -f filename -bios

EDIT: Have you tried the “Easy Flash” option in the BIOS settings?

Easy flash doesn’t recognize the modded rom :(, i have tried to rename it to the original name and still doesnt work :frowning:

About the “Inter flash programming tool” could you please give me some tips? like what to download or if there is a simple video to watch? i got lost in this huge post :frowning:


Maybe Easy flash only recognizes capsulated bios. Try the attach capsule bios instead. (PS: DO NOT flash a capsule with FPT!)

K55VDAS_mod_cap.rar (2.57 MB)

It recognizes it, but it says "Old build press Enter to return" :frowning:

My current version is 411 and the one that im trying to upgrade to is 411 too :frowning:

The FPT (With the old rom) isn’t working too :S
it says" Error 367: [FPTw64.exe cannot be run on the current platform."


The version of FPT you used doesn’t match your current platform. It should be v8 for Ivy Bridge platform.

fptw64 -f K55VDAS_mod.rom -bios

OMG, it worked thank you so much you are a GENIUS !!
i never thought it would be that easy !!! Thank you thank youuuuu!!

Just one last silly question please ! where do i have the option to enable the "hot-swap" \ "hot-plug" in the Chipset tab :D?

Chipset - PCH-IO Configuration - PCI Express Configuration - PCI Express Root Port X - Hot Plug
X means you should determine which port the PCIe Wireless NIC used.

Don’t try disabling iGPU on a Nvidia Optimus (MSHybrid) equipped laptop, which relies on iGPU for video output. In most cases there’s no direct connection between the dGPU and the monitor.
