[Trlog] More on using TRlog on a WinXP machine with a thumb USB drive

[Pete Smith]

Let me just add that I have had TR running from a thumb drive all morning 
here in DEBUG mode -- over 900 QSOs per hour.  In my case, I have DOS on 
the thumb drive, because my computer -- a dirt-cheap Dell Dimension 2400 -- 
will boot from a USB flash device; the option is found by hitting F12 at 
the beginning of boot-up.

The procedure for putting a DOS boot sector and system files on a thumb 
drive, also developed and documented by KD4D, is in the February 2005 PVRC 
Newsletter, to be found at <http://pvrc.org/Newsletters/feb05.pdf>.
