BIOS management on ThinOS
This appendix describes the BIOS management on the ThinOS devices with Wyse BIOS (CMOS), or Dell Standard BIOS.
To make BIOS management consistent between Wyse and Dell BIOS, INI parameter Device=Cmos is introduced for Wyse BIOS, and
Device=DellCmos for Dell Standard BIOS.
For BIOS conguration, if the password is congured, to update any settings, the password is required to be supplied. For example,
the INI parameter to update settings must be followed with “CurrentPassword={}”. This is mandatory for Dell BIOS, and will be
implemented as mandatory for Wyse BIOS post this release.
After a File Server BIOS update to a Wyse 5010 thin client/ Wyse 5040 thin client/ Wyse 7010 thin client/Wyse 5060 thin client/
Wyse 3030 LT thin client device, due to a CMOS mismatch, BIOS management may not be possible till the user manually enters and
exits the BIOS conguration menu. This can be accomplished as follows:
• Boot unit and press Delete during boot to enter BIOS menu.
• Enter the BIOS password.
• Press F10 to save BIOS congurations and resolve the CMOS mismatch.
