After having purchased a second-hand ClearBOX 300, I uprgaded to the most recent OS 7.9 release to find the LCD readout display non-functional.
Hours of searching online I decided to see what 'yum' could install, if anything.

Please save yourselves the effort and just

yum install ezoid.x86_64

The display corrects itself upon completion

I face-palmed so hard lol

 

[root@clearbox ~]# yum install eziod.x86_64
