If the system hangs or a problem appears, the following steps must be performed:
1. Reset the CMOS-Setup (disconnect the battery for at least 10 minutes).
2. Press ESC until the system starts up.
3. Enter the BIOS Setup:
a. load DEFAULT values
b. enter the settings for the environment
c. exit the setup
4. Restart the system.
The user may access the EEPROM through the INT15 special functions. Refer to that chapter in the
BIOS/Driver/Software manual "GEODE LX800 / LX900" on the Product CD.
The system information is read-only and uses the SFI functions. Refer to the "GEODE LX800 / LX900" manual.
6.12.1 EEPROM Memory for Setup
The EEPROM is used for setup and configuration data, stored as an alternative to the CMOS-RTC. Optionally, the
EEPROM setup driver may update the CMOS RTC, if the battery is running down and the checksum error would appear
and stop the system. The capacity of the EEPROM is 2 kByte.

6.13 Memory & I/O Map
6.13.1 System Memory Map
The X86 CPU, used as a central processing unit on the MICROSPACE, has a memory address space which is defined by
32 address bits. Therefore, it can address 1GByte of memory. The memory address map is as follows:
