2.6.1 Windows 98 (only applies to Panel PC 670)
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. Please refer to the label supplied for this information. 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
. That 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 an operating panel with touchscreen front, changes can
only be made to the BIOS using an externally connected USB or PS/2
keyboard.
Following a faulty operation, e.g. uncontrolled system shutdown or power
failure, the Panel PC 670 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 operating unit 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.
Notice
If
Legacy Support
is activated in the BIOS (enabled), individual problems
may occur with specific ISA/PCI extension boards.
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.
