"Switches" passes some options to kernel. FreeDOS supports next syntax:
SWITCHES [=] { /K | /N | /F | /E[[:]nnn] }
/k forces "conventional" (XT-83) keyboard (technically: CON driver uses
INT16/0x instead INT16/1x functions).
/e used to move EBDA structure from memory top into kernel image; without
this, you can't get contiguous 736k of conventional memory, when assign
RAM (with help of EMM386) to A000-B7FF area.
/f skips 2-second delay and hint line "Press F8 to trace or F5 to skip ..."
during startup.
/n prevents usage of F5 or F8 keys to bypass startup commands.

So what is question? This is definition, how background attributes
works: unless some code change behavior of blink to bright, colors 0..7 + 8
give blinking color.

"@" before any command omits its echoing to screen. This is very often
used with "echo off" at start of most batch files.
hc> Does @if equate to If not ???
No.
