pci.ids, modules.alias and modules.pcimap can optionally be gzipped (remove the gz extension afterwards), to save space and speedup loading.

This is if you don't specify the names on the APPEND line. HDT looks for those files in the Syslinux directory by default.

The "pciids" param has problems with long filenames, so I set the filename to "pciids.gz":

Code:
LABEL hdt
MENU LABEL Hardware Detection Tool V0.4.1
COM32 /boot/syslinux/hdt.c32
APPEND pciids=/boot/syslinux/pciids.gz

In /pmagic/boot/grub4dos/grub4dos.lst

Code:
title Default settings (Runs from RAM / Ejects CD)\n * Parted Magic version: 5.5

instead of the correct version 5.10

AND

Code:
kernel /pmagic/bzImage iso_filename=ubcd51a1.iso


instead of the correct
Code:
kernel /pmagic/bzImage iso_filename=ubcd51a2.iso


for every entry in this file.


In /pmagic/boot/isolinux/isolinux.cfg
Code:
* version: 5.5, (C) 2010, Patrick Verner


instead of the correct version 5.10.

In /pmagic/boot/isolinux/isolinux.cfg
AND in /pmagic/boot/syslinux/syslinux.cfg

both have:

Code:
APPEND iso_filename=ubcd51a1.iso


instead of the correct

Code:
APPEND iso_filename=ubcd51a2.iso


for every entry in those files.

The "VMALLOC=256MiB" is present in the syslinux.cfg only. (I'm not sure if this should be valid for the other files too).

So, it seems the syslinux and grub4dos files under pmagic were not updated for ubcd51a2 and PMagic 5.10.

The scripts under \ubcd\tools\ include:
Code:
SET VOLUME_ID=UBCD51a1

instead of the correct:
Code:
SET VOLUME_ID=UBCD51a2
.

From mkfdubcd.cmd:
Code:
VOLUME_ID=FDUBCD140

instead of the correct:
Code:
VOLUME_ID=FDUBCD141
.

For the pmagic discrepancies, I will try to work them out in the next alpha.

For the tools discrepancies, I will fix them in the next alpha. Problem is I wrote a script that tries to change the version string in the various related files automatically, but there were some bugs that I didn't catch.

Thanks!

Set the Volume Label for the FDUBCD floppy image:

The mlabel (mtools suite) command adds a volume label to a disk. Its syntax is:
Code:
mlabel [-vcsn] [-N serial] drive:[new_label]

       Mlabel supports the following options:

       c      Clears an existing label, without prompting the user

       s      Shows the existing label, without prompting the user.

       n      Assigns a new (random) serial number to the disk

       N serial
              Sets  the  supplied  serial  number. The serial number should be
              supplied as an 8 digit hexadecimal number, without spaces

http://www.gnu.org/software/mtools/manu ... html#SEC57

Generate a random serial number (only needs to be done once). Probably there is already one set in the current image, but it doesn't hurt.
Code:
mlabel -i fdubcd.img -n ::

Everytime the FDUBCD floppy version is increased, update the Volume Label.
Make the Volume Label just 11 characters long (pad with spaces): "FDUBCD141 "
For some reason mlabel doesn't pad the Volume Label with spaces, like it should do (Ubuntu includes mtools v4.0.12):
Code:
mlabel -i fdubcd.img  ::"FDUBCD141  "

This issue seems to be fixed in mtools v4.0.14 and higher, so for those versions, you can use:
Code:
mlabel -i fdubcd.img  ::FDUBCD14


For the current image, the Volume Label isn't set correctly.
Quote:
This 11 byte long string should match the volume label entry in the root directory. If no such entry is available this field should contain the string 'NO NAME ' (11 bytes long string). When updating the volume label, both, this field and the entry in the root directory should be updated.

http://www.maverick-os.dk/FileSystemFor ... ystem.html

In the FDUBCD floppy image the Volume Label field in the boot sector is empty (11 spaces), while the Volume Label in the root directoy is NwDsk340.
Code:
mlabel -i fdubcd.img -s ::
Volume label is NwDsk340

It seems the problem is Windows (I did NOT check several different versions, so this may vary). Apparently, when you select the "properties" of a floppy (or floppy image) in Windows Explorer, and there you set the "VolumeLabel" (at least for the first time), the "VolumeLabel" is set in the "RootDirectoryEntry" only, but not in the boot sector.

Another usefull command is:
Code:
minfo -i fdubcd.img  ::

or with hexdump of the boot sector:
Code:
minfo -v -i fdubcd.img  ::

minfo will show the Volume Label set in the boot sector only.
while mlabel displays the Volume Label set in the FAT root dir.

For the original FDUBCD image of UBCD v5.1 alpha 2:
Code:
$ minfo -v -i fdubcd.img ::

Plop Boot Manager 5.0.12 released

The licence has been changed for 5.0.12. The boot manager is still free for personal and non-commercial use, but not free for commercial use! Maybe I give 5.0.12 free for commercial use in the future, but not now.

New:

* Hotkey ALT-u: Select/skip usb device before its fully identified.
* Ignore USB devices: Use USB Mass Storage device has been replaced with this new feature to ignore any usb device. This should avoid hangs on builtin webcams.
* Booting from 2nd, 3rd or 4th hard disk activates now an int13 driver that swaps the hard disk drive number.

Updates:

* Boot manager init routine updated.
* Some USB driver updates.
* Better MAC support.
* Bugfix: The hang when using CTRL-u to boot another usb drive than the first one is fixed.
* plpcfgbt updated for "ignore usb devices".
* plpcfgbtGUI updated.
