ext/NTBOOT new 821416 Jul 1 11:16 NTBOOT

[msetzerii]

Just noticed the new grub4dos-for_UEFI-2023-07-01.7z has this new NTBOOT in ext directory that greatly increases size of file.
Just wondering what it does, and when is actually needed?
Significant size change.

There is a description in ext

In update log all I see are changes in menu.lst

Is there another page rather than
fef1eec#diff-eae884e96ce2e00bfac7acc7f86b3157ce9f9f7b48da48881c2abf5f4bae3d5fL118-R131 that has info??

Seems a very big ext file comparted to all the others?
Thanks for quick reply.

There is a txt file in the ext directory with instructions for use.

[yaya2007]

find --set-root /efi/grub/ext/NTBOOT

find --set-root /boot/imgs/winpe.vhd

Rename NTBOOT to NTBOOT.org and to NTBOOT.lzma then uncompressed.

NTBOOT: DOS/MBR boot sector MS-MBR XP "j" "j" "j", disk signature 0x11222211; partition 1 : ID=0x4, active, start-CHS (0x0,2,1), end-CHS (0x60,1,16), startsector 32, 12288 sectors

No NTBOOT in non-uefi 7z file?
I create a 64M boot image that contains two linux kernels and both the regular grub4dos and grub4dos-uefi boot loaders.
Before the zipped files were about 49M total with two kernels and ramdisk.lzma. Then it increased to like 51M.
Include the two grub4dos 7z files, and then the expanded versions for booting.
So, was just noticing the size increase, and probable not needed for my use, but minor increase in size.
Just wondering? Sure others might find it very useful.

[yaya2007]

Sorry, I'm very sorry! The explanation text did not follow the release, the error was in compiling the script.
ChangeLog.txt

[msetzerii]

Nothing to be sorry about. Just noticed the relatively large increase in size, and wondered what the new NTBOOT was.
Looked at the ChangeLog.txt. Had to use translate.google.com to make any sense of it. Since my image uses both the regular grub4dos and grub4dos-EFI with only regular linux kernels and memtest86+ doesn't make a difference.
Thanks again for the time.

Google Translate version.
