Hello and thanks for your reply!

Unfortunately, I have no option to change IRQ or slot for net
card. The PC I have is EliteGroup i-Buddie A530. It is
notebook-like PC with everything on-board and simple BIOS setup.
I can not even turn off the sound card - it's integrated into
chipset and BIOS has no option to change anything except LPT
settings, HDD recognition (auto/manual) and language (US/Brasil)
:)  I tried Windows 98, 2000, XP, Linux (Mandriva 9,10, Debian,
SUSE 9,10) - all hardware works just fine, even modem! But FreeBSD
4.11, 5.4, 6.0RC1 can not use netcard, and PC hangs if atapi DMA
turned on (this happens with BSD only!!!). Here are some details
(as I mentioned, sound and network share IRQ 5):
