E2B v1.78m Beta

Because grub4dos can accept up to 32-pixel high characters (I have only tested 24 so far), I have now deprecated the FONT24 variable and instead we should use FONTH=24 to use 24-pixel high fonts in E2B:

Example 1 (default)
# use E2B default 24-pixel high fonts (loads simplified Chinese + terminalbold.f24)
set FONTH=24

How to boot Clonezilla (and other stuff) from your E2B USB drive even if it does not have Clonezilla on it!

iPXE is an internet boot protocol. It allows you to download into memory and then run various payloads (ISOs) from the internet. This means you can boot stuff without it even needing to be on your USB boot drive.

You can add the iPXE boot ISOs to E2B and when you boot, they will connect to the internet (you need a network connection on that computer) and then download a menu.

To get started, just add the netboot.xyz.iso file to your \_ISO\MAINMENU folder and run it.
The current list of supported downloads is here.

E2B v1.78l Beta

Wonko (from reboot.pro) has provided some large 'European' font files for use with the FONT24 variable in E2B. They seem to support the various E2B languages OK including Russian (let me know if there are any characters missing!).

More fonts may follow!

New changes since last E2B v1.78k are:

  • Extra xxxx24 font files have been added to the \_ISO\e2b\grub folder (the font file sft has been renamed to sft24, and yxt to yxt24).
  • The \_ISO\docs\Templates\LargeFonts\MyE2B.cfg file has been updated - it now uses the new terminalbold24 font file (copy it to the \_ISO folder to use it).
  • Latest version of grub4dos added (still a few niggly bugs though).
  • \_ISO\docs\E2B Utilities\Protect\Protect.cmd script added.
The Protect.cmd script can be used to protect your \_ISO\MyE2B.cfg file. It uses cacls to remove permissions (so not accessible), sets the hidden and system attributes and compresses the file using LZMA to make it less human-readable. The file will only be accessible to it's 'owner', Protect.cmd also unprotects the file if you wish (but only if you are the owner).



If you edit the Protect.cmd file, you can change the cacls setting so that the only person that can access the file under Windows, is you, the 'owner' (i.e. someone who has logged on to your system with your account login or your Domain login). This makes it very secure (on Windows systems) but might be inconvenient.

It is not impossible for an Administrator to gain access to the file however, if they know how!

E2B v1.78k

This version has the latest grub4dos which fixes a few small bugs in previous Beta versions (in particular if you are using the FONT24 feature).

E2B v1.78j with large font support

Recent versions of grub4dos 0.4.6a support 24x24 pixel fonts.

I have added two font hex files to E2B v1.78j and also added some menu support for it.
The two font files added are fxt and sft (traditional Chinese and simplified Chinese, I think?) - they also support English characters but not other language characters, because they do not contain any special characters such as umlaut Ü, etc.. Also, the odd English character may be missing too, e.g. ~.

Because these font are bigger, it means there are less rows and columns on the screen.

800x600   = 33 columns by 25 rows
1024x768 = 42 columns by 32 rows

E2B v1.78i Beta available

This version has the latest \grldr grub4dos 0.4.6a file (not the final version yet but seems to be fully working).
The splashimage --animated command now supports up to 999 animation frames.
The frame file names can be in  xxxxxx01.bmp format or xxxxx001.bmp format.
You can download the new DNA_Animation.zip file and add it to E2B v1.78i. It will now display all 120 frames of the rotating DNA model in a smooth continuous loop.
I have also added a 'ls' menu entry to the Utilities Menu in v1.78i.

E2B Beta v1.78g now available

E2B v1.78g uses a new grub4dos 0.4.6a version which is not compatible with the previous E2B 1.78 Beta versions when using the STAMP and ANIMATE variables.

Note: See also this blog post for a 120-frame animated model of DNA!

If you are updating an earlier v1.78 which used STAMPn or ANIMATE, please check your MyE2B.cfg file and change the STAMPn and ANIMATE variables - otherwise you may not see any background and other strange things may happen!

E2B v1.78g is in the Alternate Download Areas as usual (see side panel in this blog).

N.B. The syntax has now changed slightly!

For STAMPn we need to add an extra parameter because STAMPs now supports transparent backgrounds:


Note: The top STAMP1 and STAMP2 have a transparent background!

E2B v1.78f available

YaYa has suggested that we could create a floppy disk image (.ima) file containing the animation bitmap files and load the floppy disk image into memory using:

map --mem --read-only /bitmaps.ima (fd3)
map --hook

This means that the files will be quickly accessed from memory and makes for much smoother animation with no continuous access to the USB drive (it can even be unplugged and the animation will still play).

E2B v1.78e Beta available

Yaya has fixed the problem of the hotkey app disabling animation.
This new E2B Beta version has the new grub4dos version which lets us have an animation playing on the menu.
Copy the \_ISO\docs\Templates\Animate\MyE2B.cfg file to \_ISO to test it out!

New features documented on this page.
