5.5.3 IT8888 DDMA
NOTE:
Five PCI-104 devices can be stacked onto the NANO-GX motherboard. If
these devices are stacked onto the board, the ISA DDMA channel support
should be enabled if the PCI-104 requires the allocation of that channel. If no
PCI-104 devices are being used, disable all the channels. Disabling these
channels frees up system resources that can be allocated to other system
applications.
Use the IT8888 DDMA menu (BIOS Menu 10) to enable or disable the DDMA channel
allocation for the PC-104 devices.
