4GB ISO File Size Limit

[cdob]

Again, not tested so far.

Vista / Windows 7 textmode boot directories and files are:

boot sector

\bootmgr

\boot\

\efi\

\sources\boot.wim

This should be within first 4GB of media.

Does anybody use 'oscdimg -yo' ?

For images larger than 4.5 GB, you must create a boot order file (Bootorder.txt) to ensure boot files are located at the beginning of the image. For example,

oscdimg -m -n -yoC:\temp\bootorder.txt -bC:\winpe_x86\etfsboot.com

Where bootorder.txt contains the following list of files.

boot\bcd

boot\boot.sdi

boot\bootfix.bin

boot\bootsect.exe

boot\etfsboot.com

boot\memtest.efi

boot\memtest.exe

boot\en-us\bootsect.exe.mui

boot\fonts\chs_boot.ttf

boot\fonts\cht_boot.ttf

boot\fonts\jpn_boot.ttf

boot\fonts\kor_boot.ttf

boot\fonts\wgl4_boot.ttf

sources\boot.wim

bootmgr is not listed. The boot sector use BIOS to seek this file.

Hence a friendly BIOS is expected, some BIOS may fail.

It maybe nice to add bootmgr too.

By the way:

There is no file size limit at ISO9660:1988.

A file can exist of several sections, each below 4GB.

The OS concat single sections to one file.

Old NT4 does list a PB file at ISO9660:1988.

UDF supports medium sized files.

WAIK oscdimg.exe does support UDF files greater 4GB, but ISO9660 files below 4GB.

In fact, I was able to get my 64GB key working! I had to use the HP USB key format utility to format it NTFS first, then I used diskpart to set the partition active, copied the files (I have a WIM file with all the Vista, 2008, and Win7 versions I have to install as one install.wim on a Win7 install ISO I'm using on the key now), and then after running bootsect it works. To verify, I used the diskpart method entirely to create partitions and format, and it *didn't work* for whatever reason. Perhaps there's something specific with this Patriot USB key that required the hackery, or perhaps not, but it's working now. I have an ~10GB WIM on the key and it installs everything properly, so it can be done.

I split the file install.wim in install.swm and install2.swm

In the first dvd I have the complete structure of the dvd and sources I have copied the file install.swm in the second dvd I created the directory sources and here I have copied the file install2.swm

Unfortunately it does not work the first dvd:

I copied the first dvd file Autounattended.xml, and 'he the problem?
