In their own words
Ultimate Boot CD
Ultimate Boot CD (UBCD) gathers floppy-based diagnostic utilities into one bootable ISO. After starting from the CD, users choose a program from a text menu; that program runs from a virtual floppy created in memory. The collection includes stress, memory, disk-health, and GPU testing tools. The listed release is V5.3.9, described as a maintenance release while the project says it is largely in hibernation. UBCD does not support UEFI boot, and its download guidance recommends enabling CSM Boot on UEFI machines. USB-memory boot is described as experimental on supported hardware. The download page publishes MD5, SHA1, and SHA-256 checksums for the ISO and distributes it through P2P plus volunteer HTTP mirrors. Utilities include freeware, shareware, and open-license programs with differing terms; some freeware bars commercial redistribution. Instructions explain how to customize a disc. UBCD Live is a separate early-beta Debian-based rescue CD. The listed plan is a free 803 MB ISO download.
