How to use the ISO image file to guide the system experience skills

For those who do not have a floppy drive installed, most will choose a virtual floppy drive, but unfortunately the capacity of the virtual floppy drive is too small, so the function has to Subject to some restrictions.

ISOEMU is a more interesting software. After installation, you can boot the system with the ISO image file on the hard disk, so you don't have to use the disk when installing Linux. The principle is to use GRUP to boot the ISO file on the hard disk. Of course, this ISO file is still created as a virtual CD-ROM to boot the system. It supports FAT32 and NTFS file systems, but only supports access under pure DOS, that is, based on INT13h. Disk access.

The role of each file in the ISOEMU package

ISOEMU is completely free, and friends who need it can download it from here, and release the compressed package from the download. This includes 5 files and the function of each file. As follows:

IELDR: The main program of ISOEMU Loader.

isoemu.ini: IELDR configuration file.

isogrub.iso: A bootable ISO image file provided by a software developer. This file is very small, only 1.3MB.

eltorito.sys: The optical drive driver, in conjunction with mscdex.exe, can access the virtual CD-ROM created by ISOEMU under pure DOS.

ReaderME.txt: Readme file.

Booting the system with ISO image files

If you are using the Windows 2000/XP operating system, you can use the NTLDR menu to load the IELDR. The steps are as follows:

Step 1, release the program file

Copy the IELDR file to the root directory of the C drive, the purpose is to add ISOEMU to the OSLoader of Windows 2000/XP; release the two files of isoemu.ini and isogrub.iso Copy to the root directory of the C drive.

Step 2, modify the boot.ini file

Open the Boot.ini file in the root directory of the C drive with Notepad, add the following content in the last line, of course you can also enter other Content: c:/IELDR="boot from ISO image file".

Step 3, modify the iseemu.ini file

By default, ISOEMU will start the built-in isogrub.iso image file boot system, of course we can also start other ISO image files, but The last line of the iseemu.ini file must be modified. Note that only the 8.3 file format can be used, otherwise it will not be recognized correctly.

With the help of the contents of the isogurb.iso file, you can add some common DOS external commands or third-party tools through WinISO and other software, and then save them again.

Restart the system, you can see the newly added option in the boot menu from the ISO image file, you can use the isogrub.iso image file to boot the system, the next operation is no longer said. But it should be noted that ISOEMU is still a virtual operation after all, so we don't have to expect too much speed. Rich Shell Operations

Before the ISO image file is booted, press the Alt key to enter the ISOEMU shell mode, or the error will automatically enter the Shell mode for other reasons. Here, we can get higher control with the corresponding command:

HELP: View help information.

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

CLR: Set the screen color.

CD: Change the current directory.

CLS: Clear screen.

DIR or LS: These two commands have the same function. They all list files in the current directory. Different colors are displayed here. Blue indicates a folder, white indicates a normal file, and green indicates executable file.

DRV: Replace the drive letter. The ISOEMU virtual disk number is 0xee.

RUN: You can directly run the files in the ISO image file.

BOOT: Add parameters to start other media. For example, hdd is booted from the hard disk, fdd parameters can be booted from the floppy drive, and cdrom can be booted from the CD.

LH: Load the Diskemu.bin image file in the high-end memory, and call the INT88H interrupt.

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