Thank you for purchasing this product.
The following description is a supplementary explanation for API-CNT(WDM).
Please refer to Online Help(CCNT.chm) for
how to use API-CNT(WDM).
- Notes
=======
In the following cases, the maximum size of the buffer for bus master is limited.
In Windows 64 bit OS and Windows 32 bit OS, PAE (Physical Address Extension) is enabled.
In Windows 64 bit OS or Windows 32 bit OS, PAE (Physical Address Extension) is enabled,
and [Memory Reclaiming] functionality is enabled by BIOS setting of the PC (matherboard)
in which a board is plugged.
* According to PC (motherboard), there is the case that [Memory Reclaiming] functionality
cannot be changed to Enabled/Disabled by BIOS setting, therefore, please confirm in advance.
* Up to 2 Mbyte for Windows 10 Version 1703 and later, up to 1 Mbyte for earlier OS.
