Is PowerCore Firewire running under Windows 8? Is Windows 8 supported at all?
First, please note that the future development of the PowerCore platform ceased in 2011. This means there's no official support for Windows 8.
However, if you would like to use a firewire based Powercore it's necessary (in most scenarios) to use the legacy firewire driver to get it working properly. Since Windows 8 doesn't offer the legacy firewire driver anymore, following steps are required:
NOTE: YOU DO THIS AT YOUR OWN RISK - BACKUP CRITICAL DATA FIRST - YOU WILL REDUCE THE SECURITY OF YOUR PC BY ALLOWING ANY SELF SIGNED DRIVER TO INSTALL!
A) Get yourself access to a Windows 7 computer, if you are running Windows 8 32-bit then you need Windows 7 32-bit; if you are running Windows 8 x64 you need files from a Windows 7 x64 computer. Locate these files from a Windows 7 machine:
Copy all these files into a folder of your choice on your Windows 8 computer.
Then follow this guide on how to reboot without driver signing enabled:
Once you have rebooted with driver signing disabled you can proceed.
You can then go into Device Manager:
- Expand IEEE 1394 Host Controllers
- Right click on your firewire controller and choose Update Driver Software
- Click "Browse My Computer for Driver Software"
- Click "Let me pick from a list of device drivers on my computer"
- Click Have Disk
- Click Browse
- Browse to the folder where you placed the Win7 FW drivers and click Open.
- You can then install the 1394 OHCI (Legacy) driver.
- Windows will warn you about unsigned drivers, just accept and continue the install.
B) You can enable test mode in Windows 8 which will remain persistent on reboots, however although test mode will load self signed drivers it will not load unsigned driver. Once you have installed the legacy driver in unsigned mode, reboot, the driver will fail to load and you will have no sound. To signed the driver for use in test mode, please continue with the steps below:
Open command prompt as Administrator.
Run the following two commands, both should say The Operation Completed Successfully (if not you probably didn't run command prompt as Admin)
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON
Download this http://www.mediafire.com/?hjjjj4y2n1w (if for any reason this link dies then google dseo13b.exe)
Run the download and choose to sign a system file.
Type in C:\Windows\System32\DRIVERS\1394bus.sys
Click OK and the file will be signed for use in test mode.
Run the program again and choose sign a system file
Type in C:\Windows\System32\DRIVERS\ohci1394.sys
Reboot and voila! The drivers load and no need to keep rebooting into unsigned mode.
