Aside from Kit's question, the following code will show what the difference is.

sysuse auto, clear
xi, noomit: reg mpg i.rep78, nocons
xi: reg mpg i.rep78, nocons

Contrary to your experience with -dv-, whatever that is, the second statement *does* drop a dummy.

Both the following regressions yield no-constant results without
dropping any dummies, but the p values are different for some of the
dummy variables:

xi, noomit: dv iv i.dummies, nocon
xi: dv iv i.dummies, nocon

But what is the -dv- command? -findit dv- finds naught.
