Regarding the Canoscan scanner 8400F, you're best off trying either 8400F Scanner Driver Ver. So apparently i would just get the run-around by contacting either Promise or Asus about this driver.

Also, there is no plan at present to support Vista on any Socket 939 (A8 series) motherboard, in either 32 bit or 64 bit versions, largely due to a lack of solid driver support. You will need to contact Promise to see if/when such a driver may be available. You have to register to view these but i figured i might as well link them incase they're of any use to resolving this problem.Īsus does not write driver software, we receive it from the hardware/chipset manufacturers of the components we use, and simply repackage them with the Asus installer/logos in some cases. This will need to be supported thru your mainboard manufacturer Moreover all driver support for this product is not available thru promise because this chipset is imbedded on your mainboard.

No we do not have or plan to release 64 bit drivers that will allow your 378 chipset to work as a regular IDE drive as that chipset is RAID only and not dependent on the driver. The driver works great otherwise, but every time i reboot I'm required to press F8 and choose to disable digital signature enforcement or i receive an error: "0x0000428 \Windows\system32\drivers\vide圆4.sys Windows cannot verify the digital signature for this file." The problem with this driver is that the transfer rate is limited to 150 Kb/s so I'm left with the previous drivers mentioned which were designed for XP 圆4 but work on Vista when digital signature enforcement is disabled. I'm not sure if the laptop company made the driver or if Promise did, but everything about them surfaced here Ĭurrently there is also a Vista version of this driver which apparently originated from Vista 5744 and bypasses digital signature enforcement. It was originally hosted at - but that URL no longer exists because they removed the file. It's happening for me because Promise () makes no compatible 378 IDE driver for 圆4 OSs and Vista x86/圆4, so I'm left with no choice but to use a driver which originated from a laptop called D900T () that happens to work on 圆4 OSs and on Vista 圆4 when digital signature enforcement is disabled. My situation on Vista is the same Cukkas is experiencing more or less.
