I was trying to mount my Pegasus2 R4 with Big Sur ver. 11.2.1 on iMac, but failed.
I installed the driver from the promise webpage(6.2.16) following the instruction, but could not see the disks. I then tried to manually load it as seen in following screen capture, but could not any change (still not loaded).
