[CentOS] Unusual question

Hi Mark, we can do some checks ...
[ starting from https://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.8 ]

1. No versions of CentOS 6 will work with Secure Boot turned on.
Secure Boot must be disabled to install CentOS 6. Take a look at
CentOS Bug #6321
2. On Intel (and also AMD based) processor architectures, CentOS 6
requires PAE support for 32-bit x86 chips, following the upstream's
requirement
3. Content for both the i386 and x86_64 architectures is split into
two DVDs. All basic server and basic desktop installs only from DVD-1

Looking at the CPU HW specs it's a 64 bit (x86 compatible) CPU ...
https://ark.intel.com/it/products/128984/Intel-Pentium-Silver-J5005-Processor-4M-Cache-up-to-2-80-GHz-

it seems that your Intel processor is supported by Centos 6.x (and
also 7 and 8...)

Centos 6.8 is quite OLD, so why don't you try at least the 6.10 release?

Have you got any issue installing/using that?

Give us some evidence of the problem you have so we can help
specifically on that item

Cheers,
Fleur
