Solution:

Rev. .2.0 has different setting for choosing boot device as you use SRAM, EPROM, Flash or DOC-2000. Because DOC-2000 simulates HDD, please set the first boot device to SCSI or IDE-0. SRAM, EPROM, and Flash are used to simulate FDD, Please set first boot device as FDD. Also please note that: 1. Set boot device to "FDD" and the standard CMOS must set FDD to 1.44M or not work. 2. Disable the boot FDD seek or system will tell you FDD error as system boot up. Since EPROM is use to simulate FDD, please set 1st boot device to "FDD" and disable item " Floppy drive seek" form advance CMOS setting. After you press ALT-S entering the on board flash rom disk configuration window, Please set SSD to drive 1ST if you need a boot disk. Because the on board flash rom disk only simulate as a FDD, you need to boot from A drive. It can never boot as a C: drive. Please do not use C and E memort segment on bios Rev. 2.0. If you use BIOS rev. 1.0, then you can use E sigment.
