Hi all,

I've got a problem that really is a hassle.

I use a FreeBSD 2.2.1 box that dual boots with Win 95/DOS for Internet
access.

Of course Win95/DOS is used for playing the odd game :)

The machine has a 3Com 3c503 Ethernet card, a SB16 card, and a joystick
all attached.  

IRQ's used are as follows. 
3Com (ed0) is on IRQ 9 (3-5,9 are the only valid IRQs)
SB16 (not used under FreeBSD yet) is on IRQ 5 and will be used under
FreeBSD on the same IRQ.

Anyway, after using FreeBSD and rebooting (using reboot not shutdown)
whichever devices relying on an IRQ FreeBSD has used fail to operate
under DOS or Win95.

Does anyone know of a way I can fix this problem aside from disabling
all the devices ?
