It's a compatibility issue between KYRO II Card and 4GB system
memory. Change the AGP Aperture Size setting from default 64M to
256M can fix the problem.
Also please mention that the maximum DDR memory support of KG7
/ KG7-RAID is about 3.5G rather than 4G. This limitation is caused
by PC architecture and the missing 0.5G memory address is reserved
for PCI I/O space, AGP aperture mapping space and other onboard
device I/O space, so, although the AMD761 datasheet exclaims the
memory support is up to 4GB, actually the system only use about
3.5GB with four 1G DDR memories installed. In another word, BIOS
and operation system will report about 3.5GB only.
