:My question: How can I check if the A-drive is pressent before DOS

  I'm surprised this one got past the moderator, as it's not really about C
at all.  This more or less falls under comp.os.msdos.programmer, where I'm
sure they'll tell you to intercept INT 24h and the AH and DI registers
contain the information about the critical error.
