UBCD plugin UBCD4WIN: Some portions of UBCD5RC1 do not work

I have another good one..

As a standalone ISO, this all works fine. When used in a multiboot configuration from UBCD4Win there are a few problems. Namely PMagic 4.6 will not boot, and Avira cannot find its scanner or vdf files.

PMagic:

Avira Rescue:

Details of build:

Here are the UBCD4Win plugin files that launch UBCD5RC1

ubcd5.inf

Code:

ubcd_grub4dos.ini

Code:

title Ultimate Boot CD for DOS 5.0
ls /images/ubcd5.iso || find --set-root /images/ubcd5.iso
map /images/ubcd5.iso (0xff)
map --hook
root (0xff)
configfile /ubcd/menus/grub4dos/main.lst

default_grub4dos.ini

Code:

default 0
timeout 0

I have grub4dos, syslinux and isolinux directories defined in my main BCDW.ini plugin

Any ideas?

UBCD50RC1 works fine. It is the UBCD4Win UBCD plugin that sucks.
It just assumes that you can rename the ubcd50RC1.iso file to ubcd5.iso.

This is not the case. Parted Magic needs to find the ubcd iso, to find the rest of its files.
In the Syslinux config file for Parted Magic, you can find:

Code:

LINUX /pmagic/bzImage
INITRD /pmagic/initramfs
APPEND iso_filename=ubcd50RC1.iso acpi=off edd=off noapic load_ramdisk=1 prompt_ramdisk=0 rw vga=791 sleep=10 loglevel=0 keymap=us

The 'iso_filename=ubcd50RC1.iso' parameter specifies the iso name Parted Magic will look for. If you edit this parameter on the fly with the 'e' command of grub4dos to 'iso_filename=ubcd5.iso', Parted Magic will boot (Parted Magic will look in /, /images and /pmagic for the iso file).

Renaming and mapping the iso will work for all dos based tools, but not for all linux tools (except if they need only a kernel and initrd, which is the case for almost all tools included in UBCD, except Parted Magic and Avira Rescue CD).

Avira Rescue CD won't work with iso mapping (without patching).
You can extract the /antivir dir of the UBCD50RC1 iso and place it in the root of your CD or USB partition.

Someone made a patch to Avira Rescue CD a while ago, to support iso mapping:
http://forum.avira.com/wbb/index.php?pa ... adID=88261

Complain to Avira, but don't expect that they will include it.

Also ubcd_syslinux.ini could be made a bit better (boot the isolinux menu instead of the grub4dos one):

Code:

LABEL UltimateBootCD for DOS 5.0
  KERNEL grub.exe
  APPEND --config-file="timeout 0;default 0;title UltimateBootCD for DOS 5.0;ls /images/ubcd5.iso || find --set-root /images/ubcd5.iso;map /images/ubcd5.iso (0xff);map --hook;root (0xff);chainloader(0xff)"
  TEXT HELP
  Runs UltimateBootCD for DOS 5.0
  ENDTEXT

BCDW is a very old boot loader (and isn't updated anymore). I don't recommend it.
Which version of ISOLINUX does UBCD4Win use?

Ah that makes sense, I don't use UBCD50RC1 "out of the box" and recreate the UBCD ISO with a generic name counting on the assumption that I can just "patch" the extracted UBCD ISO contents as updates become available. I'll modify the pmagic\boot\syslinux\syslinux.cfg AND pmagic\boot\isolinux\isolinux.cfg to use the generic ISO name given to UBCD during my build process and hope I don't forget this hack after future updates.

I'll look into the Avira patch and see what happens. I realized all of this yesterday as I was attempting to remove viruses from a friend's machine and spent today trying to find out why these things didn't work and at first blamed my USB device.

I'm not sure which version of ISOLINUX I put in my bcdw directory (not an out of the box UBCD4Win option), how would I find out? I assume I can update to whatever is current because UBCD is the only plugin that relies on it.

Can you upload the ISOLINUX.BIN file somewhere?

Here it is

**link removed**

I tried modifying my ubcd5_syslinux.ini as suggested;

Code:

LABEL UltimateBootCD for DOS 5.0 
  KERNEL grub.exe 
  APPEND --config-file="timeout 0;default 0;title UltimateBootCD for DOS 5.0;ls /images/ubcd5.iso || find --set-root /images/ubcd5.iso;map /images/ubcd5.iso (0xff);map --hook;root (0xff);chainloader(0xff)"

I get a grub4dos reboot loop, so I reverted back. Just thought I'd report on the result of your script change.

I'm not sure where to begin integrating this patched version, it only includes grub4dos as is. Anyone have any experience adding this patched version?

Read the ReadMe.1st file:

If you are technically interested or want to inspect my "work", here is a list of my changes :

- in folder "/etc/init.d" (bash scripts) : halt (CD tray function), delay (new, necessary for new "halt"), shell
- in folder "/etc/init.d/rescue (bash scripts) : boot, bootupFunctions (key to my work)
- in folder "/bin" (bash scripts) : mount_all (device detection), load_modules (progress bar)
- additional Linux programs : "/bin/nano" (Editor), "/sbin/reboot"( which does, what its name indicates)
"/bin/ctrlaltdel" (quick reboot in console mode with the classical keys)
- Replacement of syslinux/isolinux bootmanager with Grub4DOS

These files can be found inside the initrd_0.gz file (gzipped EXT2 filesystem, I think) of the testaars.iso.

I haven't had any luck with this, and have given up on the idea.
