Cmos Setup Harddisk List; Eeprom Saved Cmos Setup - DIGITAL-LOGIC MICROSPACE PC/104 Technical User's Manual

DIGITAL-LOGIC AG
WARNING:
On the next Set-up pages (switched with PgDn and PgUp) the values for special parameters are
modifiable. Normally the parameters are set correctly by DIGITAL-LOGIC AG. Be very careful in
modifying any parameter since the system could crash. Some parameters are dependent on the CPU
type. The cache parameter is always available, for example. So, if you select too few wait states, the
system will not start until you reset the CMOS-RAM using the RAM-Reset jumper, but the default val-
ues are reloaded. If you are not familiar with this parameters, do not change anything.

CMOS Setup Harddisk list

− Use type 48 and type 49 for user defined harddisk entries. Enter the sectors, cylinders and the
number of heads.
− Press F1 for autoidentifying the harddisk, after the user defined HD 48 or 49 is selected.
− With type 48, the Plug & Play feature is also enabled.

EEPROM saved CMOS Setup

The EEPROM has different functions, as listed below:
• Backup of the CMOS-Setup values.
• Storing the keymatrix definitions, if the hardware supports a keymatrix (MSM386SV, MSM386SN,
MSM486SV).
• Storing system informations like: version, production date, customisation of the board, CPU type.
• Storing user/application values.
The EEPROM will be updated automatically after exiting the BIOS setup menu. The system will oper-
ate also without any CMOS battery. While booting up, the CMOS is automatically updated with the
EEPROM values.
Press the Esc-key while powering on the system until the video shows the BIOS message and the
CMOS will not be updated.
This would be helpful, if wrong parameters are stored in the EEPROM and the setup of the BIOS does
not start.
If the system hangs or a problem appears, the following steps must be performed:
1. Reset the CMOS-Setup (use the jumper to reset or disconnect the battery for at least 10 minutes).
2. Press Esc until the system starts up.
3. Enter the BIOS Setup:
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 the chapter SFI
functions.
• The keymatrix is defined with special EDITMATR.EXE and SAVEMATR.EXE tools.
• The system information are read only information. To read, use the SFI functions.
