Ubcd download

UBCD V5.0.0 is now available for download.Torrent: ubcd50.iso.torrentmd5sum: d667b52a34a7fe75d64ab94e12097cda sha1sum: b805801112eaaf055ff3a41871955f7a908a8425OK, this is the final FINALrelease of UBCD V5.0, warts and all. This is slightly different from the version posted here. Here are the changes:- Updated UBCD FreeDOS to V1.37. \ubcd\custom\custom.ini is processed together with \ubcd\dosapps\ubcd.ini. Also added "-m" to "mdiskchk.com -b" else the ubcdcmd= parameter passed to the ISO is not detected.- Added missing rm.exe and cat.exe to \ubcd\tools\win32\unxutils.- Updated HDClone to V3.9.1.- Updated SeaTools for DOS to V2.20.- Updated AVIRA AntiVir Rescue System to V3.6.9-20100512182845.The first change lets you isolate custom FreeDOS apps to "c:\ubcd-extracted\ubcd\custom", instead of having to modify "c:\ubcd-extracted\ubcd\dosapps".The second change adds some missing files so that the antivirus scripts can run.If you have the older ubcd50.iso (md5sum: 8ca82598a488b6fffc4173bf7af419ad), you can download this 20+MB xdelta3 file and patch the old ISO. You need the xdelta3 EXE from here.Type:Code: Select allxdelta3 -d -s ubcd50.iso ubcd50.xdelta3 ubcd50final.isoto generate "ubcd50final.iso" and check that the md5sum is "d667b52a34a7fe75d64ab94e12097cda".

To do this change the following in the /ubcd/menus/syslinux/memory.cfg:From:Code: Select allCOM32 linux.c32 /ubcd/boot/memtest86p/memtest86p.binTo:Code: Select allLINUX /ubcd/boot/memtest86p/memtest86p.binBest regards,Nelson ady Posts: 832 Joined: Sat May 08, 2010 5:26 am Re: UBCD V5.2b3 available for download #4 Post by ady » Thu Feb 07, 2013 4:36 am Is there any reason not to edit /boot/syslinux/syslinux.cfg ?***The (sed) scripts for syslinux2grub4dos need several corrections.***I insist that the content of /pmagic/boot/syslinux/ is mostly unnecessary. Pmagic's syslinux.cfg is originally pointing to /boot/syslinux/, whether explicitely or with relative paths. As in past betas, you have edited the (relative or absolute) paths to point to /pmagic/boot/syslinux/, and in some cases that's correct (for the message*.txt, for example), but for the syslinux-related files, that path edition is not the best option.Just as an example, with the recent changes to UBCD's cfg files (using some relative paths) a similar edition would be needed by someone adding UBCD to a multiboot UFD, IF all files were to be copied to some "/ubcd/" subdirectory (as you do with "/pmagic/").Moreover, by using this duplicated Syslinux-related files, if PMagic updates its Syslinux version, UBCD 5.2 will fail to chain to it when a user updates pmagic in UBCD.That's why I already suggested a generic procedure to update pmagic in UBCD (in which, BTW, I forgot to post about the additional boot entries that also point to pmagic's syslinux.cfg).

Why the need to edit this file?The (sed) scripts for syslinux2grub4dos need several corrections. Could you provide more details?Just as an example, with the recent changes to UBCD's cfg files (using some relative paths) a similar edition would be needed by someone adding UBCD to a multiboot UFD, IF all files were to be copied to some "/ubcd/" subdirectory (as you do with "/pmagic/"). In this case, the "pmagic" folder should be left in '/' and all should work fine.Moreover, by using this duplicated Syslinux-related files, if PMagic updates its Syslinux version, UBCD 5.2 will fail to chain to it when a user updates pmagic in UBCD. We will cross that bridge when we come to it.

Boy, sed is difficult to debug! Took me awhile with this thing.I don't understand what you mean. I just gave an example of a potential case with duplicated files. I think what you mean is this: Code: Select allMULTIBOOTCD \distro1 \distro2 \ubcd \pmagic* \ubcd \pmagic resulting in duplicate files.To me, this makes no sense at all. The right layout should be: Code: Select allMULTIBOOTCD \distro1 \distro2 \ubcd \pmagic* ady Posts: 832 Joined: Sat May 08, 2010 5:26 am Re: UBCD V5.2b3 available for download #10 Post by ady » Tue Feb 12, 2013 6:04 pm Victor Chew wrote:I don't understand what you mean.

The right layout should be: Code: Select allMULTIBOOTCD \distro1 \distro2 \ubcd \pmagic*No. What I meant was that IMO it makes no sense (and it even has some disadvantages) to release something like:Code: Select allMULTIBOOTCD \boot\syslinux\ \distro1 \distro1\boot\syslinux\*.c32 \distro2 \distro2\boot\syslinux\*.c32 \ubcd \ubcd\boot\syslinux\ \pmagic \pmagic\boot\syslinux\*.c32 if the content of each "boot/syslinux/" are mostly many duplicated files. Or, specifically for our case, I meant that IMO it makes no sense to release something like:Code: Select allMULTIBOOTCD \boot\syslinux\*.c32 \ubcd \pmagic \pmagic\boot\syslinux\*.c32 (and iso*.* and memdisk)if "\pmagic\boot\syslinux" has duplicated files as in "\boot\syslinux".But, the worse case for Syslinux files is having in "\pmagic\boot\syslinux" many of the same Syslinux-related files as in "\boot\syslinux" but in a different version(s). That would make the "\pmagic\boot\syslinux\syslinux.cfg" file unusable to boot pmagic's kernels.Please note that when I say "duplicated" files here, I am referring to Syslinux-related files only. I am NOT talking ipxe, mhdd, plpbt, pxelinux, sgd or whatever else. Those might or might not be duplicated, but they are not worth the effort. The Syslinux-related files (iso*.*, *.c32, memdisk,...) are not just a question of waste, but about correct functionality.One potential solution: in "\pmagic\boot\syslinux\syslinux.cfg", keep pointing to "/boot/syslinux/*.c32" for c32 modules and for memdisk only; while using "/pmagic/boot/syslinux/*" for specific pmagic's files (not Syslinux files), as, for example, pmagic's syslinux.cfg file, message*.txt, ipxe, hdt, mhdd,... Then delete the relevant unnecessary files from "/pmagic/boot/syslinux/*".In the UBCD52b2 topic I gave a different alternative too (which is even better IMO). The relevant unnecessary files (that can and should be deleted) are also listed there.

If the next release of Parted Magic breaks the status quo, I will find other ways to work around the changes, all the while maintaining my original goal (as little change

As possible).It is not my objective to worry about the addition of other distros to UBCD. I will leave the modding and optimization to the person doing that.

I am not talking about the distro (pmagic) itself, nor about any of its extra tools.But this seems to offend your sense of aesthetics! Not at all. I am not talking about aesthetics. I am talking about functionality.Victor Chew wrote:For me, my primary goal is to make as little change to the Parted Magic distro as possible to while integrating it into UBCD.I agree with the goal, and by using "/boot/syslinux/" for PMagic's Syslinux-related files, you would be making the same amount of changes, or even less. In PMagic, the original path is already "/boot/syslinux/" (whether in absolute or in relative notation). You are currently changing it to "/pmagic/boot/syslinux/", and I suggest keeping "/boot/syslinux/" where it points to Syslinux-related files. For the files that come from PMagic but not from Syslinux, keep changing it to "/pmagic/boot/syslinux/" as done in the betas.(Hey, I'm not suggesting to correct the wrong directives that are sometimes part of the original PMagic file; so even those are left without change. )If the next release of Parted Magic breaks the status quo, I will find other ways to work around the changes, all the while maintaining my original goal (as little change as possible).My point being, you can already avoid having to deal with such situation, and still keep that original goal.It is not my objective to worry about the addition of other distros to UBCD. I will leave the modding and optimization to the person doing that.I am talking about PMagic in the official release of UBCD, not about anything else.In fact, you already perform the same type of editions for other utilities. Sometimes the relevant cfg file needs little editions, and sometimes it doesn't, but you are not adding Syslinux-related files for each utility included in UBCD. Furthermore, adding them would break UBCD, as each utility comes with different versions of Syslinux. To make it work consistently, UBCD must centralize and unify those Syslinux-related files. I am suggesting to do exactly
