Hi, Alexander
    Will you please confirm whether the system can work well although the following message is complained?
    >Phoenix BIOS detected: BIOS may corrupt low RAM, working around it

    It seems that the low 64K memory is reserved after the above message is complained.

Thanks.

No. It won't slow down your PC. The only issue is that the lower 64K memory can't be used.

Maybe there exists an unknown issue when accessing the lower 64K memory. So it is marked as reserved. But in fact the 64K memory size won't affect the performance of the system.

Thanks.
