Can't get floppy drive to work

[Ken Wilson]

I have RH 6.0 and am trying to get my floppy to work from dos. All it does is lock up the machine so I have to reboot it to regain control.   In the  /etc/dosemu.conf file, I set the line   $_floppy_a="threeinch:/dev/fd0" as the comments suggest.  My floppy works fine in Linux and I have unmounted it before trying to run dos.   when I type a:  or dir a: or anything with an a: in it, the machine keyboard locks up so I have to do a re-boot to get control again.   It must be something simple, but I have read through every doc file and HOWTO manual I can find and little is mentioned about the floppy drive other than what I have done.   any help or ideas would be appreciated.   thanks ken
