Hello! I run XP on QEMU 0.9.0 with sound (FreeBSD 6.2, KQEMU 1.3.0.p11). As it is mentioned in the QEMU FAQ, the driver for es1370 is automatically installed by Windows. Probably this applies to 2003, too. qemu -hda winxp.img -m 256 -soundhw es1370 -localtime -net nic -net user -cdrom /dev/acd0 HTH Jan Henrik
