BIOS with bifurcation feature enabled?

In the BIOS upgrade section ( Installing OS - Seeed Wiki ) there is a mention to contact email address sbc@seeed.cc in case I want a BIOS with bifurcation feature enabled.
But the email address is not valid according to the error email notification I have got from SMTP server responsible for domain “seeed.cc”.

Anyone with an idea whom to contact or (even better) where to download this kind of BIOS?

Thanks.

Hello @Rado1,

I have sent you an email with the BIOS. Please check.

Thank you.
