Hi

I have latest WDK and I have VmWare 7 Workstation. I'm running XP SP3 32 bit. With these features, could I somehow manage to test and run my 64bit driver for example in Win7 or even XP 64 bit ?

Thanks

Hi,

If your hardware support x64 then you can install guest x64 O.S in VMWare and test your x64 binaries on it, even if host O.S is 32-bit .

Hello,

You may also want to take a look at QEMU and Bochs. I have not tried either, but QEMU should be able to emulate an x64 CPU.

Thanks,

How to do it in Vmware? Is there any manual or PDF about it? I was not able to install 64 bit OS in it when I'm in 32 bit host.

Does your hardware support x64 ?

[LiatLevontin]

Yes, my hardware supports 64 bit

You have to enable VT extension in your BIOS settings .

VmWare x64 emulation speed and work with VmWare can be very slow on x86-32.
I suggest you install x64 Windows and then use VmWare.

Do the development in 32 with a final test and install in 64 bit. Properly written, the driver will not care whether it was built for 32 or 64 bit. Remember, however, that you must address the requirement to sign a 64 bit driver with a Class 3 code signing certificate. 64 bit XP through Win7 will not load an unsigned driver. For testing, you can attach a WinDbg host and set Test signing on via BCDEDIT. You can also generate your own test certificate for testing, but a release version installed on a "customers" system will require a certificate and all cross-certificates from Microsoft.

You may also use my patch, it will disable PatchGuard and driver signing for Windows 7 X64 RTM. SP1 is not supported, yet.
