   I'm interested in GNU/Linux OS distributions allowing classic BIOS boot.   
   In 1997 college computer science, I started with *BSD UNIX & Slackware   
   GNU/Linux, and those still allow.  They say 'if you try Debian, you learn   
   Debian; if you try RedHat, you learn RedHat; if you try Slackware you   
   learn GNU/Linux', and similarly (learning less than Slackware) for   
   anything newer.  I tried Debian, RedHat soon after, then many.  These are   
   ones I tried or am trying, but apparently some (for example GNU/Linux   
   Mint) assume you boot UEFI and to boot classic BIOS you must customize   
   manually... am I right (or is there some installer shell preferably non-   
   network command?) and which current of these force UEFI or otherwise   
   manual customization, and which (I will state some) can you still boot   
   classic BIOS just with installer (maybe even shell non-network command)?   
   Please don't call classic BIOS 'legacy' as that's vague and sounds people   
   who created it are dead, and that companies use planned obsolescence and   
   want to force buying new hardware.
