  • UBCD V5.0b5 available for testing

    For those of you who have been waiting, I apologise that the next release of UBCD is taking so long. There was supposed to be V4.2, but that got scrapped. Then V5.0 went through a couple of generations, but with the support of new developers (as702 and IceCube), I think it was worth all the trouble. Anyway, the mainline release is not available yet, but for those of you living on the cutting age,

  • Patch file for UBCD V4.1.0

    The first patch file for UBCD V4.1.0 has just been released. It fixes two problems: 1) error in DFT's disk image filename 2) errors in the DOS boot disk menu. http://www.ultimatebootcd.com/download.html#xdelta.

  • UBCD V4.1.0 is released!

  • Changes to UBCD web forum

    I have finally bitten the bullet and upgraded the web forum to the latest version of phpBB, dropping the m2f module in the process. The m2f module makes pretty deep modifications to phpBB's core, which makes it more difficult to update phpBB regularly. By dropping m2f, I hope I can keep phpBB more up-to-date. What does all this mean to you? It means you will no longer be able to subscribe or...

  • Patch file for UBCD V4.0.3

    The third patch file has been released. Some unnecessary files are removed under \dosapps\mcafee in order to increase the amount of free RAM disk space so that ubcdvir can run successfully for McAfee Antivirus. You can find the patch file and instructions at: http://www.ultimatebootcd.com/download.html#xdelta.

  • Patch file for UBCD V4.0.2

    The second patch file has been released. It increases the default RAM disk size on DOSUBCD.IGZ so that updating F-Prot's virus definition files through autovir or ubcdvir can complete successfully without running out of disk space. You can find the patch file and instructions at: http://www.ultimatebootcd.com/download.html#xdelta.

  • Binary patches for UBCD

    I will be releasing binary patches to fix bugs in the original UBCD ISO image. This allows me to issue updates faster because the patch files are typically quite small, so I can afford to host them myself instead of propagating the changes to the mirrors, which takes a lot of coordination and time. The first patch file has just been released. It updates memdisk to a more current version that...

  • UBCD V4.0 is released!

    For better or for worse, I am making UBCD V4.0 available for download today after a short beta test. This released is based on syslinux/isolinux instead of CDShell. I am abandoning the latter due to its lack of further development, while syslinux/isolinux is still undergoing active development, so there is a better chance that syslinux/isolinux will work with newer machines. There is also...

  • MD5 and/or SHA1 checksums for files

    It would be nice to verify that the UBCD module is unmodified, especially considering one is security related...

  • Help required for testing

    I am considering making the new boot disk based on LZ-DOS (Russian MS-DOS 7.10 compatible kernel with LFN-support) default for the next release of UBCD, instead of the current one based on FreeDOS. According to Erwin, the maintainer for the DOS boot disks for UBCD, the LZ-DOS boot disk has "sharper" memory properties and hence should be better for running DOS apps. If you would...
