Custom / CUSTOM

Specs: Windows XP, Q6600/4.00 GB PC8500
I recently bought myself a Logitch MX 5500 becuase my old logitech's keyboard failed on me.

Now, Everything went perfect and stuff, but when I reboot into BIOS, I can't control the computer's Splash and I can't access the BIOS.

Is there a way of installing a driver in the BIOS to enable Bluetooth Mouse/Keyboard Support? Or is there a way of treating this mouse and keyboard like a none-bluetooth device just for the BIOS?

My motherboard is an ASUS P5Q Deluxe Motherboard.

Please Help.

The setting in the bios Setup USB Legacy Devices or USB Keyboard or similar has to be enabled for you to be able to get into the bios Setup with a USB connected mouse - that is enabled by default in newer bioses, NOT enabled by default in older bioses. You can change the bios setting by connecting a PS/2 keyboard, which always works to get into the bios, or if the default is that's enabled, if it's disabled you could remove the Cmos battery, wait a few minutes, re-install it, or clear the Cmos by moving a jumper on the mboard, waiting a few minutes, moving it back (you'll need to set at least the date and time in the bios Setup, save settings, the first time you boot after that in both cases).
See the manual for your mboard model.

On the other hand, I have no idea whether you can get into the bios with any wireless keyboard, that of course has a USB connected transmitter / receiver.

You usually cannot use a mouse of any sort in the bios Setup.

I think USB Emulation is already enabled. Its just that it worked with my old Logitech Wireless device which was a USB Device, but not a bluetooth device.

If it has an external USB connected transmitter / receiver, it's detected as a USB device . I've never seen any setting regarding bluetooth in any bios.

It kind of works in BIOS, but my P5Q Motherboard doesn't let me use the Flash OS, I can press escape (sometimes it freezes that as well) but after the 10 second countdown, I can press the DEL button and then go into BIOS.

OK, then it sounds like the bios takes a short time to detect the wireless keyboard's USB receiver / transmitter while booting, but it does detect it / the wireless keyboard after that.

I downloaded the manual for your P5Q Deluxe and looked at it.

As I expected, there is absolutely no mention of bluetooth in it. There is also no mention of wireless keyboards or wireless mice in it, but it does mention things about wireless network adapters.

By the way, most if not all wireless keyboards and mice use bluetooth - they typically have a range of up to 30 feet max or so, which is the limit for bluetooth - if they used e.g. wireless G, you could use a wireless keyboard or mouse a lot farther away from the transmitter / receiver.

What are you referring to?

It's NOT a good idea to attempt to flash the bios unless you MUST. Flashing the bios is the riskiest thing you can do with a computer ! Bios flash chips can only flashed a small number of times - sometimes the flash chip fails physically the FIRST time you attempt to flash the bios - if the flash chip fails physically, your computer will never boot again after that until the flash chip has been replaced - on many mboards these days the flash chip is soldered into the mboard and can only be replaced by an expert - it's often cheaper to replace the mboard. .
There is nothing mentioned in the release notes for the bios updates for this mboard that mention anything to do with bluetooth or wireless anything.

The manual was made in 2008, so the bios supports booting from bootable USB drives, if the settings in Boot are correct for that, if that applies (they may be recognized automatically regardless of the Boot settings) .
However, if there is a Windows operating system on the USB drive that is 2000 or later, you get a blue screen 0X0000007B error = INACCESSIBLE_BOOT_DEVICE when you try to boot from it - it's difficult to get around that problem - Microsoft doesn't want you to be booting from removable drives that have 2000 or later on them.

The manual says you can't flash the bios using an update on a USB drive in any case unless you're using Vista (or, probably, Windows 7).
