Ever since I have had my A1XE, it seems to have very high CPU usage. Playing video especially will peg the CPU at 100%. I am not using any of the onboard devices except the NIC.
Startech PCIUSB7
EIDE SIIG
SoundBlaster Live 5.1
It seems disk transfers are using PIO but says UDMA is available. Can I force it to use the SIIG in DMA mode with something like "nvsetvar sii0680_xfer GGGG"?
