BIOS management on ThinOS
This appendix describes the BIOS management on the ThinOS devices with Wyse BIOS (CMOS), or Dell Standard BIOS.
To make the BIOS management consistent between Wyse BIOS and Dell BIOS, an INI parameter Device=Cmos is introduced for Wyse
BIOS, and Device=DellCmos for Dell Standard BIOS.
If the password is congured for the BIOS conguration, then you must enter an appropriate password to update any settings. For
example, the INI parameter to update settings must be followed with “CurrentPassword={}”. This is mandatory for Dell BIOS.
After you update BIOS on Wyse 5010 thin client, Wyse 5040 thin client, Wyse 7010 thin client, Wyse 5060 thin client, and Wyse 3030 LT
thin client by using le server, the BIOS management may not be possible until you manually enter and exit the BIOS conguration menu.
This is due to a CMOS mismatch. To resolve this issue:
• Boot unit and press Delete during boot to enter the BIOS menu.
• Enter the BIOS password.
• Press F10 to save BIOS congurations and resolve the CMOS mismatch.
