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 experimental support for running UBCD from a USB memory stick via a modified version of the UBCD2USB script, which has lurked around in the forum for quite a while now.... read more
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 like to help with the testing, you can download a minimal boot CD at:... read more
Another bug report for V3.4. The launch commands for NWDSK and MSRRC are mixed up. Please refer to:
for more information.
A patch file is available to fix it, but you must be able to create a customized UBCD ISO image. Thanks to kustner for reporting the bug.
First bug report for V3.4. Please refer to Bugs and Workarounds:
for more information. If this affects you, a patch file is available to fix it, but you must be able to create a customized UBCD ISO image. Thanks to Erwin Veermans for reporting the bug.
After a long gap, Ultimate Boot CD Ver 3.4 is finally ready for download!
There is the usual update of apps to their latest versions. Erwin Veermans has
added a new feature on the FreeDOS bootdisk that allows you to update the virus
database for F-Prot, McAfee and AVG over the network. A new expert mode has also
been added (by pressing the [Ins] key at the menus) that allows you to choose
which boot disk (FreeDOS, OpenDOS or MSDOS) to use when running certain apps if
you encounter compatibility issues.... read more
Stephen Stagg has kindly set up a BitTorrent tracker for UBCD. As such, I have added the BitTorrent seeds back to the download page.
The mailing list function of the web forums stopped working around two weeks back due to some server misconfiguration. I have fixed it this morning, so the few of you who are subscribed will start receiving forum postings again. Sorry about that. I will go through the forum postings I have missed and reply as necessary.
I am back at working on the next release of UBCD, in case you are wondering. I had to move to another apartment last week, and that did mess up my daily routine somewhat, but worse, my new place does not have always-on connectivity. So I have to remove the torrent downloads since I am no longer able to run the tracker. As always, I can't seem to find a reliable public tracker to use, so the torrent downloads stays down unless you have better ideas.
I must apologise for not being too responsive with emails and forum postings over the past two weeks. The reason is because I was assigned to a "special" project at work which was supposed to take only one week, but now looks like it is going to take a month instead. This project has been sapping up all my energy and time, leaving me with little else to attend to other matters. But once this is over and done with, I promise I will be back to more important things, like releasing another version of UBCD!
I am debating whether to revert back to CDShell V2.0.11 (the version used in UBCD V3.2) for the next version of UBCD. The reason why I am considering is because there is a problem with CDShell V2.1.6 which prevents it from booting on some machines. The author knows about it and has encountered it himself, but there is no newer version to fix it yet, nor are any definite schedule to do so.
But going back would mean big changes again to the menu files (mainly the syntax for bcdw booting and parameter passing), as well as the loss of certain functions (booting of certain ISO images from diskemu).... read more
I have written a new tutorial (http://www.ultimatebootcd.com/pm8.html) on how to add the Partition Magic 8 rescue disks to the UBCD. Your comments and feedback are welcomed. Meanwhile, a reminder that the tutorial section is still wide open for more contributions. Anything from adding applications to the UBCD, or how to use particular apps on the UBCD for system recovery etc. will be great!
I have updated the version of mkisofs on the Customizing UBCD page (http://www.ultimatebootcd.com/customize.html) to Ver 2.01. This version does not have any dependency on cygwin.dll, so I have updated the customization instructions to reflect it. Thanks to Techarium for the suggestion.
I am pleased to announce the release of Ultimate Boot CD Ver 3.3! This release is based on the new CDShell V2.1.6 and BCDW V2.0a1. It adds AVG Free Edition, CHZ Monitor-Test, Necromancer's DOS Navigator, GRUB, Eraser, FileLink, QwikTest and D-Browse. It updates various other applications to their latest releases, and refreshes the virus definition files. Please refer to the release history for details. At the moment, only the BitTorrent and PlanetMirror sources are up, but more mirrors should become available shortly.
I have created a new tutorial section:
to consolidate all the contributed tutorials. Meanwhile, if you have some spare time, why not write up a new tutorial for the benefit of all? Anything regarding burning, using or adding stuff to the UBCD is fair game.
My webhost is not too happy with people running PHP-based trackers (they consume too much CPU and bandwidth) and has sent a cease-and-desist warning email. So I am transiting the tracker over to my home machine. The torrent files have been updated to point to the new tracker location, but I will leave the PHP tracker running for a few more days before taking it offline. Meanwhile, if you hit any problems with the new tracker, please let me know.
The web-based forums (http://www.ultimatebootcd.com/forums) are now officially open for business, and will be used in the future for obtaining support, reporting bugs and suggesting software to be added to the UBCD. They will replace the existing ubcd-support and ubcd-suggestions mailing lists (but not ubcd-announce, which will continue to operate as is).
I am back! Please be patient and give me some time to clear the emails in my inbox. Thanks!
I will be going for a well-needed vacation for the whole of next week. Should you send me any email during this period, please expect some significant delay in my reply because I may be on the road, or I may not have Internet access at where I am staying at that time. In addition, I will not be able to update the website while I am gone, so all update requests will have to wait until I am back. Thanks for your kind understanding!
OK, the three primary mirrors are up. Let the download frenzy begin!
Thanks to all who emailed me to tell me my tracker wasn't working! Not sure what happened, but my BlogTorrent configuration settings got corrupted somewhere along the way (it was OK last night) and I couldn't even login to the tracker. So I reinstalled BlogTorrent from scratch, and things appear to be moving along now. Please try again and let me know.
The mirrors are still being updated and should be up very soon.
Things got a little slow after the festive binge, but we have finally recovered enough to release Ultimate Boot CD Ver 3.2! This release fixes all the bugs found in Ver 3.1. It adds the following programs: Avast, AntiVir, MHDD32, Ontrack Data Advisor and XOSL. It updates quite a number of programs to their latest releases. The virus definition files have also been refreshed to the latest versions. Please refer to the release notes (http://www.ultimatebootcd.com/history.html) for the gory details.... read more
The primary website at SourceForge has been down for the past couple of days. The reason was because I was experimenting with rsync, and one of the sessions on WinXP messed up the file permissions (whereas the same program running on Win2K worked fine). Everything is back to normal now. My sincere apologies to all who were inconvenienced!
Another bug has been reported on UBCD Ver 3.1. Please check out the Known Bugs page (http://ubcd.sourceforge.net/bugs.html) for more information and workaround.
Two bugs have been reported on UBCD Ver 3.1 so far. Please check out the "Known Bugs" page for more information and workaround.
