Upgrade BIOS
on the Wyse 5470 All-in-One Thin Client
This section describes the procedure to update
BIOS on the Wyse 5470 All-in-One Thin Client by using file server. The Dell Standard
BIOS file is converted to BIN file format for signature and security

For example, 5470AIO_bios.bin. The BIOS version may be updated in each release. For the latest
version of BIOS, see the latest Dell Wyse ThinOS Release Notes.
Upload the BIOS file to folder WNOS in the file server—ftp
or https.
Ensure that the INI parameter autoload is enabled for firmware update in WNOS.INI.
Restart the
thin client.
The BIOS is updated automatically.
To verify
whether the new BIOS is updated correctly, from the desktop menu,
click the System Information option, or click
the System Information icon in zero mode. In
the Event Log tab, the BIOS version log is
displayed.

BIOS setup, do the following:
Restart the thin client,
and during system boot, press the F2 key.
