Summary	08313: sf2049te, sf2049tea: Game crashes when accessing self-test
Description	sf2049te and sf2049tea are unable to access the self-test in MAME. Looking at the serial console on ttys00, the game kernel panics when trying to check the CD-ROM device on pci:05.0:ide:1 and eventually resets itself. sf2049 and sf2049se do not exhibit this issue.
Steps To Reproduce	Set Console Enable DIP to "Yes" and Test Mode DIP to "EPROM-based Test", then reset machine. The game will always watchdog reset after it says "Clean up scratch files.OK" Set slot device pci:00.0:ttys00 to "terminal" and reset machine to see kernel messages.
Additional Information	I found a bodge fix: In pci-ide.cpp, line 58, changing "hdd, cdrom" to "hdd, hdd" allows the self-test to successfully boot on a self-compiled version of MAME, as hdb is now a disconnected HDD device. The game should be able to handle a CD-ROM device as the secondary IDE device, though, and that patch seems like it would break other things.
