Solution:

1. To boot from Flash Chips 29C040A or 28SF040 (must use BIOS Rev.sr2.30), SRAM and EPROM, The drive assignment must be "A", because the SSD (Solid State Disk) can olny emulate these chips as a FDD drive. If you set the SSD to other drive 2nd, 3rd, or 4th. It is not bootabel but accessable. You may use one, two, or three chips but must be install in sequence of socket U4, U11,and U12. Socket U4 is the one closest to LPT port. So if you use DOC-2000, please put it in U4. 2. To boot from DOC-2000, DOC-2000 will be boot from drive letter C: 3. The general setting to use SSD are : a. Check the jumper setting JP21(I/O Address), JP23(U4),JP24(U11),and JP25(U12) for SRAM battery. b. Enabel the "Internal Flash/ROM disk" from "Chipset Feature Setup" in CMOS setting. C. After reboot you will see " Internal Solid State Disk BIOS....... SSD assigned to X: Hit if you want to setup SSD Please type ALT-S to enter the setting. Select : SSD IC type: SRAM 128K CXK681000P EPROM 128K 27C010 FLASH 128K AT29C010 SRAM 512K CXK684000P EPROM 512K 27C04f0 FLASH 512K AT29C040, 28SF040. DOC-2000 Memory segment windows D000-CFFF, D400-D1FF, .....etc. SSD Driver Emulated. 1st, 2nd, 3rd, 4th, DOC-2000 You can use HDD or FDD to boot and then format the dirve. 4. For non-DOC-2000 chips use DOS command: Format drv:/u/n:9/t:40 (For 360KB disk) Format drv:/u/n:18/t:80 (For 1.44M disk) Even use one chip in U4. format 1.44M command is suggested. You can ignore the bad sector. 5. For DOC-2000 please refor to the procedure down below. Please use ######## Installation DOC-2000 in CPU card ########### The following steps is the procedure of installation: (1). Put a DOC on ROM 1 socket ( the first ROM socket ). (2). Choose a suitable SSD I/O address for yo
