- UltraBay: no hot swapping
- UltraBay Thick: thicker version of UltraBay to support CD-ROM drive
- UltraBay II: supports hot swapping, blending has cut out edge on the right
- UltraBay FX: the combined floppy drive and CD-ROM, DVD or CDRW mechanism found in the 390/390E/390X
- UltraSlimBay: supports hot swapping; frame, rectangle like blending
- UltraBay 2000: supports hot swapping; frame, blending has cut-out edge on the right
- UltraBay Plus: same as UltraBay 2000, but can take the UltraBay Plus Device Carrier which in turn can hold the UltraBay Plus c500 Cradle or the UltraBay Plus Numeric Keypad
- UltraBay Slim: supports hot swapping; notably thinner than the UltraBay 2000, cut-out right edge in blending
- UltraBay Enhanced: supports hot swapping; slightly thicker than UltraBay Slim, but accepts UltraBay Slim devices
The pinout switching is done by the BIOS and hardware, so that it is completely transparent to the operating system.
- Floppy drives are supported by the standard floppy driver.
- ZIP drive support is possible through the ide-disk driver.
- IDE hard disks and optical drives are supported by the ide-disk or ata_piix driver in the linux kernel. SCSI emulation via ide-scsi is possible.
- Batteries are automatically handled by the hardware, but can be controlled further by using tp_smapi.
- UltraBay Plus devices should be handled by the USB subsystem, but if the actual devices are is not known.
A CDRW/DVD-ROM Superdrive (scavenged from a Mac iBook) will fit in an Ultrabay 2000. The original face won't fit in the bay, leaving a bare metal front. When the drive spins up, it blows a lot of air out. Maybe that's an anti-dust measure?
In general, Ultrabay 2000 CD drives have a standard connector, and can therefore be replaced by most other 12.7 mm drives. You might have to do some cutting of the plastic face plate.
The Ultrabay Slim CD drives however, have a proprietary connector. You can not replace them with any 9.5 mm CD drive.

- IBM originally used the spelling UltraBay with a capital B and later switched to Ultrabay with a lower b. We are sticking with the capital B here.
