I am reasonably sure a Floppy drive does not exist for the UltraBay Slim. People are told to use a USB FDD instead.
Also the UltraBay 2000 battery is not supported in UltraBay Plus. UltraBay Plus has its own battery that should be used
Anyone know if it's possible to bodge together a 770X Ultrabay II CD-RW from a Ultrabay II DVD and, say, a 600E UltraSlimBay CD-RW? Just something I've been wondering for a while.
Does it seem odd that the UltraBay II was the first bay? Was there no UltraBay, or some other type of bay? -- Whizkid 00:51, 16 Apr 2005 (CEST)
True. ;-) It seems, that actually the drive bay in the 380 models was called UltraBay, but i don't know for sure. So i didn't add it.

Not just IDE
Obviously UltraBay is not just an IDE interface.
Most also have a floppy interface (apart from the latest 'slim' and 'enhanced' versions), and can take a battery.
If I remember correctly you could get the floppy drive activated by hibernating the thinkpad and installing the floppy drive, so that on power up the BIOS would enable the floppy disk drive and it would work. This was in the old APM days, so it might work differently with ACPI.
You're right. I remember reading some IBM text about the UltraBay yesterday, which said that the controller is capable of dynamically changing the pin layout to support the different kind of devices (initiated by the BIOS). I'll try finding it again and correcting the information on the page.

The oldest references I can find to the name 'UltraBay' are the ThinkPad 755 series (755CSE, 755CE, etc).
But the older 750 models already had the hot-swappable drive bay, and support some of the same options, so it looks like the 'UltraBay' started with the 750 series.
But then again, later models support CD-ROM drives (755CD, 760CD, etc), which certainly are not supported in these older models, but they are all called 'UltraBay'.
My understanding of the original Ultrabays is as follows:
- 360, 360C, 360Cs, 360P, 360CE, 360CSE, 360PE
- 750, 750C, 750Cs, 750P
- 755C, 755Cs, 755CE, 755CSE, 755CX
- 760C, 760L, 760E (thin model)
- Devices (probably not all devices are supported in every ThinkPad):
- 1.44MB FDD
- 2.88MB FDD
- Cellular Digital Packet Data (CDPD) - not compatible with 360P, 360PE, 750P
- IBM Wireless Modem for ARDIS
- TV Tuner (NTSC)
- 2nd HDD
- 2nd Battery
- PCMCIA Cartridge
UltraBay - Thick
- 755CD, 755CDV
- 760CD, 760LD, 760EL, 760ELD, 760E (thick model), 760XL, 760XD
- 765D, 765L
- Supports UltraBay devices, in addition to:
- CD-ROM drive
