The News about WIN Max 2021 from the indigogo page
WIN Max 2021 has been shipped,
and the system firmware, driver package, and BIOS firmware have also been synchronized to the official website.
Because the machine has a built-in "one-key restore", you don't need to download the firmware deliberately.
This firmware can only be used after you have replaced the SSD.
The prerequisite for upgrading this BIOS is that you have replaced the SSD, and the SSD is the WD series SN550 or SN750.
It fixes problem that the SSD cannot be found after restarting (not turning it off and then on again).
This problem is because the WD series SSD takes a long time to power up, which causes the BIOS to fail
to find the hard disk device after restarting, and then the boot jumps to the EFI or BIOS interface.

Please note: If you have not replaced the SSD, please do not upgrade the BIOS firmware.
