Boot from an ISO file located on a FAT32 partition
===================================================

This zip package contains 5 files, they are:

ieldr        - IsoEmu, the loader, main program

isoemu.ini   - configuration file for ieldr

isogrub.iso  - demo iso file(Boot Grub)

eltorito.sys - Let dos know there is a CD inserted.  ;-) Thanks Mr. Bart.

ReadME       - IT's me



Known Limitation
=================

* Support FAT32 partition only;

* Works on x86's RealMode only(so this cannot boot Windows PE,
           OR, WinNT based OS), `cause it hooks INT13h;

* Support 8.3 file format only;


HOW TO USE
============

A) As a menu item of NTLDR

     1). Extract ieldr to your c:\, and modify your boot.ini，add the
following line:

         c:\ieldr="Load IsoEmu Final# SV"

     2). Extract isoemu.ini and the iso file what you want to Emulate,
to the root directory of a FAT32 partition;

      -AND- change a line of isoemu.ini:

         "isoemu isogrub.iso" (modify `isogrub.iso` to your iso file)
  

Run from Grub, or Other Loader. (can run @0x0000:0x7c00, 0x0000:0x8200)

      It's simple, put the ieldr to one place where grub can found it,
and then, use:

         run (path)/ieldr          That's all!



C) Something about the internal-shell
    
    This shell is a multi-cd-loader just like Mr. Bart's DiskEmu1x. It has
many commands(for more info, type help at the prompt), such as:

      * Use "UP" key for last command;

      * Run app from a CD，i.e. 1.44M/2.88M FDD-img，or another boot loader;

      * Drv, to change the drive number of CD, it is always 0x9f in VMWare;

      * Dir/ls, list the current directory;

      * BOOT  boot system from fdd/hdd, just like:  boot hdd [CR]

      * And there is a east egg... ...


>> This program is designed for exploration; till now, there are some bugs, maybe.

Introduction
QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.

QEMU has two operating modes:
Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code.
User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API emulator or to ease cross-compilation and cross-debugging.
As QEMU requires no host kernel patches to run, it is very safe and easy to use.

                    * before launch the default loader of emu-cd, we can run into
                          the internal shell by press Alt Key;
                    * display the information of this iso file while emulating;
                    * we can display some message or pause the boot sequence,
                          before launch this CD, by put some lines after
                          `isoemu xxx.iso' line, see isoemu.ini file for detail info;
                    * if we try to rein isoemu, it will display some info, and refuse to
                          use the new one to emulate.

for internal shell, boot command can boot cdrom/fdd/hdd:

boot hdd
boot cdrom
boot fdd

@useronce:
on the link you provided there is no such file.
And the readme is also speaking about the releas from 28.Okt, which is FAT32 only...

nice project, with limitations though.
I tried my FreeDOS ISO-file (uses isolinux.bin). Fails
I tried Memtest86+ v1.27 ISO (www.memtest.org). Fails.

the provided GRUB seems to work.
CDrom needs 2048byte cdrom bootsector + a kernel (GRUB v0.95).

I still don't know what the eltorito.sys file is for (separately).
IELDR does not seem to require it, and the isogrub.iso already contains Grub + Memdisk + Win98 image including eltorito.sys
(so you're violating several copyrights, and maybe Bart Lagerweij's redistribution permissions.).

what kind of ISO's can it actually boot?
-Simple emulation (hdd, floppy) ?
-Non-emulation -> GRUB only ?

any more examples?

Keep up the good work, but do improve the compatibility.

how do I install the IELDR to an empty FAT32 partition?
I guess it needs some kind of bootsector then.

copy ieldr c:\
copy test.iso c:\
copy isoemu.ini c:\
sys c: c: bootonly /k ieldr

I tried the 2004-10-28 version.

Boot from an ISO file located on a FAT32/NTFS partition

ISOEMU 1.05th fs_fat32/fs_ntfs+ [Sinctech]by Ganstein [Final Step]

[history]
13:38 2004-11-6     5th version        - main update: NTFS +

                    * update the xchanging data code for hdd-sector => v.iso-sector;
                    * you can use your own oem-logo or internal shell(such as diskemu1x.bin) in ieldr.
                    * -=No Support=- :"

                             we can display some message or pause the boot sequence,

                             `isoemu xxx.iso' line, see isoemu.ini file for detail info;"

Ok... I'm confused.  Will it or won't it boot a pebuilder winpe ISO ? If it will, can someone post a step by step??

vcdrom --install (hdx,y)/path/to/bootable_file.iso
vcdrom --bootcd

- 1st thing, I want to say sorry to Mr. Bart Lagerweij for my violating. I'll remove

the eltorito.sys from the root of this package.

- 2nd, the isoemu is now only support an non-emu bootable cd to boot. If it is an

emu-disk, such as floppy-disk-image, or hard-disk-image, we can use

grub+memdisk to launch it (just use the internal-shell and run isogrub.bin coming

with isogrub.iso)

- 3rd, the installation is simple. We know, ieldr can run from

:       0x0000:0x7c00   -  the common address for loaders

: or_ 0x2000:0x0000   - this is the address for ntldr. ;-)

so, we can use grub(with run-command-patched by Gandalf. you can download

it from http://159.226.20.15/grub_chs/grubin/rtl8139_run4.zip, this version can

load a binary loader with max 64kb size) to run ieldr, just like:

grub> run (hd0,0)/boot/ieldr

And, we can also use the ntldr to launch ieldr, as an menu item:

c:\boot\ieldr="boot isoemu with ntfs support"

_IT_ should not be installed to disk's boot sector(s).

[2005-07-29]All of those link about 159.226.20.15 is boken, and we have a new
site hosted on sysoft.zdwx.com, so if you want to download the isoemu, visit:

http://sysoft.zdwx.com/isoemu/

Maybe I am stoned today, but seem not to be able to find any link for downloading it, all I get is this:
http://sysoft.zdwx.com/isoemu/index_eng.html

where I can find only snapshots and here are the howto's:
http://sysoft.zdwx.com/isoemu/ishell_eng.htm
I also went to the chinese page here:
http://sysoft.zdwx.com/grub/download.html

But could not find a download link.

Could you provide a direct link to isoemu and to grub?
