12 Configuration/diagnostics partition
ID 12 (decimal 18) is used by Compaq for their configuration utility partition. It is a FAT-compatible partition (about 6 MB) that boots into their utilities, and can be added to a LILO menu as if it were MS-DOS. (David C. Niemi) Stephen Collins reports a 12 MB partition with ID 12 on a Compaq 7330T. Tigran A. Aivazian reports a 40 MB partition with ID 12 on a 64 MB Compaq Proliant 1600. ID 12 is used by the Compaq Contura to denote its hibernation partition. (firstname.lastname@example.org)
NCR has used ID 0x12 MS-DOS partitions for diagnostics and firmware support on their WorldMark systems since the mid-90s. DataLight's ROM-DOS has replaced MS-DOS on more recent systems. Partition sizes were once 72M (MS-DOS) but are now 40M (ROM-DOS).
Intel has begun offering ROM-DOS based "Service Partition" support on many OEM systems. This support initially used ID 0x98 but has recently changed to ID 0x12. Intel provides their own support for this partition in the form of a System Resource CD. Partition size has remained constant at 40M. See e.g. sds2.pdf. (Chuck Rouillard)
IBM also uses 0x12 for its Rescue and Recovery partition on Thinkpad laptops. See also thinkwiki.org.
