Upgrading BIOS on Wyse 3040 thin client

This section describes the procedure to update BIOS on Wyse 3040 thin client with ThinOS, and Wyse 3040 thin client with

The Dell Standard BIOS file is converted to BIN file format for signature and security purposes. The format of the BIN file is

Wyse_3040_version.bin.

Upgrading BIOS by using file server

To upgrade BIOS using file server, do the following:

1. Download the Dell BIOS file at the www.dell.com/support.

For example, Wyse_3040_version.bin. The BIOS version may be updated in each release. For the latest version of

BIOS, refer to the latest Dell Wyse ThinOS Release Notes.

2. Rename the Dell BIOS file as A10Q_bios.bin.

3. Upload the renamed BIOS file to folder WNOS in the https server.

4. Ensure that the INI parameter autoload is enabled for firmware update in WNOS.INI.

5. Restart the thin client.

the System Information icon in zero mode. In the Event Log tab, the BIOS version log is displayed.

For example, System Version: 8.5_017 (ROM 1.2.1).

This log indicates that the BIOS version is updated to v1.2.1.

2. Enter the BIOS password, if admin password is set.
