It's been a long time since I fired up my Atari 8-bits,(Ihave a 2600,
800, 65gs, and 130xe, as well as some STs) and I've never used an XL
so I have to try and dredge up from "Mapping the Atari" which is
mainly programming-related and "Your Atari Computer " which is very
basic. I also have 810 and 1050 drives. Some applications written for
the 800 (not XL) don't support the XL but most do ( There's a
program called "Translator"). There are also differences in DOS 2.0
and 2.5 -- 18 vs 26 sector tracks. The 1050 will sense density, the
810 won't. According to the book, the XL had a built-in BASIC
although it was compatible with earlier cartridges and a self-test
feature like the 65GS and 130. This is accessed by a reset without
the BASIC cartridge, SELECTing the test and then pressing START.
  Entering DOS should bring up the 2.5 MENU which has Directory,
Format, etc as well as Load binary. pressing L will default to a
query for specs. Some programs included an autorun file or
loader program. IIRC simply entering RUN the program name
would work. You can also use OPEN #1,6,0,"D:*.*." to get a dir. read.
 Likely your best source for info is the comp.sys.atari.8bit FAQ.
Hope this helps, it's been a while and since I've been fooling with
numerous OS , it sometimes gets jumbled in my head.
