@@ -56,13 +56,21 @@ rtl8139 timer by building the port with RTL8139_TIMER enabled.
 (the rtl8139c+ that model=rtl8139 emulates needs less cpu than qemu's
 default ne2k nic which is driven by ed(4), it has not been made default
 only because it may not work with all guests yet.)
-- qemu now uses aio at least for ide dma, so if you get `Bad system call'
-crashes that is because aio is not (kld)loaded.
 - if you get repeated `atapi_poll called!' console messages with FreeBSD
 guests or other weird cdrom problems then thats probably because the guest
 has atapicam loaded, which for reasons still to be determined has problems
 with qemu's now by default enabled cdrom dma.  You can build the port with
 CDROM_DMA disabled to disable it.
-- if you build qemu wihout SDL and then get crashes running it try passing

+- physical device access (real cdrom/dvd instead of iso) seems to cause
+problems with some guests now.  If this happens to you you can make
+an iso of the disc by doing something like
+	dd bs=2k </dev/acd0 >cd.iso
+and then use
+	qemu -cdrom cd.iso ...
+instead of giving it the physical device.  (This might also speed up the
+guest somewhat.)
