I found the DEL key got me into the opening menu for the Igel 350C. This comprised five icons:
which are labelled:
What they do is self-evident. In this context SCU stands for System Configuration Utility. Selecting that gets you into the usual BIOS setup screens. As far as running an OS the firmware is EFI orientated.
Here I had plugged in a Sandisk 8GB USB drive formatted for UEFI booting. Selecting the Boot Menu icon brought up:
Boot Option Menu EFI Boot Devices IGEL_EFI_2 (MB2908) IGEL_EFI_1 (MB2908) EFI Embedded MMC Device 1 (MB2908) EFI Embedded MMC Device (MB2908) EFI USB Device (SanDisk) ↑ and ↓ to change option, ENTER to select an option, ESC to exit
Selecting the SCU option brought up the more usual sequence of BIOS screens:
Main/Advanced/Security/Power/Boot/Exit.
The BIOS identified itself as InsydeH20 Setup Utility. The 'main' menu screen is shown below.

In the Security section you can enforce/disable Secure Boot
In the Boot section you can enable/disable USB Boot. There is also a EFI submenu. This just lists the EFI devices displayed in the Boot Menu above. I'm not sure what this is there for. There is no way to select any particular entry or alter the order of the list.
I see no option for Legacy Booting anywhere.
As usual I haven't done anything with the native operating system.
