2–6 SIMATIC Panel PC 670/870 Commissioning Instructions
A5E00135748-01
2.3 Panel PC 670 – Windows 98
When the Panel PC 670 is started up for the first time, the system requests entry of
the appropriate OEM license number during the operating system boot routine.
This number is adhered to the device. After entering the license number, enter a
name for the computer so that it can be identified within a network.
Special features
The Panel PC 670 is shipped with BIOS setting LEGACY SUPPORT DISABLED.
This means the full functional range of a USB keyboard is not available during the
initial boot sequence (before Windows is started). There are no restrictions for
using a USB keyboard to make changes in the BIOS Setup. When using a touch
panel, changes can only be made to the BIOS using an externally connected USB
or PS/2 keyboard.
Notice
If Legacy Support is disabled in the BIOS, problems may occur with ISA/PCI
extension boards.
After improper operation, a faulty shutdown of the system or after a loss of power,
the Panel PC 670/870 starts the Scandisk program during the subsequent boot
routine. It is not possible for the user to stop this automatically started program
using an integrated membrane keyboard or external USB keyboard.
The following steps are recommended in order to interrupt this automatic process:
1. When Scandisk has been completed, switch the device off and on again.
Windows reboots without any keyboard input.
If Windows is not rebooted, switch the device off again. Carry out the following
steps:
2. Plug in the USB keyboard and switch on the power supply.
3. Press the "F2" key during the boot routine.
4. Select
Hardware Options in the BIOS Setup and switch the LEGACY
SUPPORT
setting to ENABLED.
The USB keyboard is also supported in Enabled mode. It is possible to
deactivate Enabled mode again.
5. After rebooting the system again, select
Hardware Options in the BIOS
Setup and switch
LEGACY SUPPORT back to DISABLED.
If Windows 98 is terminated and Start in MS DOS Mode is selected, input is
only possible using an external PS/2 keyboard.
Power management
The default Power Saving setting Disabled must not be changed in the BIOS
setup.
