Producing a tone from the speaker in real-mode is only about a dozen lines of assembler. Making it stop after N seconds is slightly more complicated, but yeah, space is not really a problem.

The space really /wouldn't/ have been a problem, because the sound continued straight on through to Windows. The technician described being in the GUI all while the PC speaker was emiting the tone. He held the phone up to the pc speaker so I could hear it. One solid tone. I don't know what that knowledge is worth, but there it is :-) --Matt -- ------------------- Matt Simmons Assistant Network Administrator 304.580.8080x5007 Fibernet LLC --------------------------------------------------------------------------- Captus Networks Are you prepared for the next Sobig & Blaster? - Instantly Stop DoS/DDoS Attacks, Worms & Port Scans - Precisely Define and Implement Network Security - Automatically Control P2P, IM and Spam Traffic FIND OUT NOW - FREE Vulnerability Assessment Toolkit http://www.captusnetworks.com/ads/42.htm ----------------------------------------------------------------------------
