the call may not be failing. What may be happening is that you saw the last successful post code; the memory is configured wrong; and the system failed when you jumped to hardwaremain. This is what makes this chipset so frustrating. > Anyone has a good idea as to why this call would possibly fail?

Often the copy operation can work but the memory will fail when the processor tries to use it for a stack, for example. Any operation that causes a burst to memory can cause trouble. The chip is EXTREMELY sensitive to the SDRAM drive level settings. ron _______________________________________________ Linuxbios mailing list [EMAIL PROTECTED] http://www.clustermatic.org/mailman/listinfo/linuxbios
