How to boot a Windows system with an ISO-mirrored file

For those who do not have the floppy drive installed, most will choose the virtual floppy drive, but unfortunately the virtual floppy disk capacity is too small, so there are some limitations on the function.

Isoemu is an interesting software that can be installed with the ISO image file on the hard drive to boot the system so that you don't have to dial it when you install Linux. The principle is to use the Grup to boot the ISO file on the hard drive, and of course still create the ISO file as a virtual optical drive to boot the system, support FAT32, NTFS two file systems, but only support pure DOS access, that is, INT13h based disk access.

Isoemu the functions of each file in a package

Isoemu is completely free, need a friend to download from here, will download the compressed package back to release, here includes 5 files, the function of each file is as follows:

Ieldr:isoemu the loader main program.

The Isoemu.ini:IELDR configuration file.

Isogrub.iso: A bootable ISO image file provided by a software developer, which is a small, 1.3MB file.

Eltorito.sys: Optical drive driver, with Mscdex.exe can access Isoemu created virtual optical drive in pure DOS.

ReaderME.txt: Readme file.

Booting a system with an ISO-mirrored file

If you are using a Windows 2000/XP operating system, you can load the IELDR with the help of the Ntldr menu, as follows:

Step 1th, Release Program Files

Copy the Ieldr file to the C-packing directory to add Isoemu to the osloader of Windows 2000/XP, and copy the Isoemu.ini and isogrub.iso two files to the C-packing directory.

Step 2nd, modify the Boot.ini file

Use Notepad to open the Boot.ini file in the C-packing directory, add the following on the last line, and of course you can enter something else: c:ieldr= "boot from ISO image file".

Step 3rd, modify the Isoemu.ini file

By default, ISOEMU will start the built-in Isogrub.iso mirrored file boot system, and of course we can launch other ISO image files, but we must modify the last line of the Isoemu.ini file, note that only 8.3 file format can be used, otherwise it will not be recognized correctly.

With the help of you feel that the contents of the Isogurb.iso file is too small, you can add some commonly used DOS external commands or Third-party tools via Winiso software, and then save them again.

Reboot the system, you can see the boot menu in the new "from the ISO mirrored file boot" option, select the use of isogrub.iso Mirror file boot system, the next operation is no longer said. But it should be stated that Isoemu is still a virtual operation after all, so we don't have to expect too much of its running speed.
Rich shell operations

Before the ISO-mirrored file Boots the system, press the ALT key to enter the Isoemu shell mode, or for other reasons the error will automatically enter Shell mode. Here, we can use the appropriate command to obtain higher control rights:

Help: View assistance information.

Date: Displays the current date and time information for the local computer.

CLR: Sets the screen color.

CD: Change the current directory.

CLS: Clear screen.

Dir or ls: The two commands work exactly the same, listing the files in the current directory, showing different colors, blue for folders, white for normal files, and green for executable files.

DRV: Replace the drive letter, Isoemu virtual out of the disk number is 0xEE.

Run: Files in the ISO image file can be running directly.

Boot: plus the parameter can start other media, for example, HDD is boot from hard disk, FDD parameter can boot from floppy drive, CDROM can boot from CD.

LH: Loading the diskemu.bin mirror file in high memory, the int88h interrupt was invoked at this time.

REBOOT: Skip the memory detection process and quickly reboot the system.
