There is a "bootindex" option that can be passed to the "-device"
parameter of QEMU.  This option give more fine grained control of boot
order.

However, the default should have been to boot from a harddrive first,
so I'm not sure why you see the cdrom first.  You could add the
following to the QEMU command line to see the seabios debugging info:
-chardev stdio,id=seabios -device isa-debugcon,iobase=0x402,chardev=seabios
