Im trying to install Win7 on my new box,blank hd and im getting a popup stating that A required cd/dvd drive device driver is missing.

Microsoft support site says that my cd/dvd drive in incompatible with microsofts AHCI driver..then goes on to say that this can usually be resolved by switching AHCI MODE to IDE or ATA mode.

Problem is I CANT find where to do this in my Phoenix bios..can someone help??
guess i'll have to buy a new cd/dvd drive if i cant switch it..?

tis frustrating,any help is appreciated.

-merlinsomeone must know!~
help meh please..I'll put a good word in for you with Santa Please don't bump your thread. If someone can help it will be posted.Sounds to me you are attempting to install Win7 on a really old machine as Win7 has native drivers for most hardware out there and will at least complete the install and allow you to update your drivers...

Is this a Pentium2 or something ? ?These are my foresee regarding to your problem.



1. I think you should be able to meet the minimum system requirements of this Operating System.



Windows 7 system requirements

If you want to run Windows 7 on your PC, here's what it takes:

1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)

16 GB available hard disk space (32-bit) or 20 GB (64-bit)

DirectX 9 graphics device with WDDM 1.0 or higher driver

Additional requirements to use certain features:

Internet access (fees may apply)

Depending on resolution, video playback may require additional memory and advanced graphics hardware

Some games and programs might require a graphics card compatible with DirectX 10 or higher for optimal performance

For some Windows Media Center functionality a TV tuner and additional hardware may be required

Windows Touch and Tablet PCs require specific hardware

HomeGroup requires a network and PCs running Windows 7

DVD/CD authoring requires a compatible optical drive

BitLocker requires Trusted Platform Module (TPM) 1.2

BitLocker To Go requires a USB flash drive

Windows XP Mode requires an additional 1 GB of RAM and an additional 15 GB of available hard disk space.

Music and sound require audio output

Product functionality and graphics may vary based on your system configuration. Some features may require advanced or additional hardware.

PCs with multi-core processors:
Windows 7 was designed to work with today's multi-core processors. All 32-bit versions of Windows 7 can support up to 32 processor cores, while 64‑bit versions can support up to 256 processor cores.

PCs with multiple processors (CPUs):
Commercial servers, workstations, and other high-end PCs may have more than one physical processor. Windows 7 Professional, Enterprise, and Ultimate allow for two physical processors, providing the best performance on these computers. Windows 7 Starter, Home Basic, and Home Premium will recognize only one physical processor.


2. Platforms status.
if your computer runs in lower version of any kinds of chips,and your system unit is too older i think you must upgrade first your hardware before you upgrade your software.

AHCI (Advanced Host Controller Interface) is present on newer Intel chipsets such as 975X (ICH7), P965 (ICH8), and P35 (ICH9). AHCI mode is enabled in the BIOS and 3 settings are commonly available: IDE, AHCI, and RAID. The last two (AHCI and RAID) require a driver floppy and the F6 method when installing Windows XP otherwise the hard disks won't be detected.

AHCI mode brings 3 main advantages:

1. Supports NCQ (Native Command Queuing) allowing SATA drives to accept more than one command at a time 2. and dynamically reorder the COMMANDS for maximum efficiency.
3. Supports hot plugging of devices
4. Supports staggered spin ups of multiple hard drives at BOOT time



Hope it will help you a little..

Problem is I cant find where to do this in my Phoenix bios

Those bios screens above doesnt look like my Phoenix bios..maybe I need to update my bios for it to read? Could I update my bios from cd or usb drive? mine is simple looking with solid blue background but with more options and no tabs at top not at home atm so cant check what version.
