After firmware version 1.65 package, Areca RAID card ARC -
1883FIRM.BIN code creates a virtual bootable disk (UEFI OS) for
the ARC-1883UEFI.BIN code to launch the McBIOS setup utility.
When user chooses to boot from the virtual disk in M/B setup, the
McBIOS setup utility is launched through boot into UEFI OS during
M/B boot. Follow below procedures to launch it.
a). Add RAID controllers “UEFI OS(Areca A....)” in the M/B boot
option: You must enter the setup of motherboard BIOS and add
UEFI OS to the boot option if your motherboard BIOS does not
automatically add it.
b). Restart your motherboard to boot from UEFI OS. The mother-
board vendors provide two methods for choosing a boot device:
Enter boot menu by using hotkey or enter boot menu through
BIOS configuration.
