Emulating IBM OS/2 Warp 4.0



































This system is tested using Bochs, and having some difficulties. Cannot click to run program. I don't know why. I will try again using VMware later.

IBM PC-DOS 1.00

Hello Guys,

My first post on emulating the DOS, would be using IBM Personal Computer DOS version 1.00 which was released by IBM in the year 1981.




...



The history says that,

IBM® Personal Computer™ DOS 1.00 was a result of the vision and efforts of many different people; including various employees of both IBM® and Microsoft®. Some would say that DOS owes a great deal more to the creator of CP/M (Gary Kildall) than either IBM® or Microsoft® would ever admit to. If you want an honest assessment, I suggest you find a group of disinterested assembly programmers to compare the code from CP/M and DOS rather than relying on Net rummors! Most would say the majority of the initial work had been accomplished by Tim Paterson, who created much of the system code while employed at Seattle Computer Products where he wrote QDOS (Quick and Dirty Operating System). Bill Gates and Marc McDonald, however, actually invented the File Allocation Table (FAT) file system for Microsoft's standalone BASIC in 1977 which Paterson later used to store and work with files under QDOS.

Apart from the DOS system code, Paterson also produced two system utilities that found their way onto IBM's diskette, the most notable being DEBUG. After Microsoft® acquired the rights to sell what was then called 86-DOS, Paterson joined that company in order to help complete their 'secret project' for IBM® (i.e., Personal Computer™ DOS 1.00). At least one other Microsoft employee, Robert O'Rear (whose name is embedded in the Boot Sector), spent a great deal of time on this project as well. There were a number of IBM employees who worked on hardware interface code, wrote applications software for the operating system and spent time testing each change made along the way (some of their names are embedded in various BASIC and system programs on the diskette).

Of the 40 files on this diskette, 38 of them can be listed using the operating system's DIR command; they all had the same date: 08-04-81. However, the two Hidden System files have different dates: The earliest file on the disk, IBMBIO.COM, was dated July 23, 1981, and latest one, IBMDOS.COM, had a date of August 13, 1981.

Enough the history, I was able to secure a copy through ***** from ***** and after doing MD5 checksum, the result is: 73c919cecadf002a7124b7e8bfe3b5ba which has the same result as Daniel B. Sedory (http://thestarman.pcministry.com/DOS/ibm100/Exam.htm)

Let have a look from some screen capture, I made through BOCHS.

Settings Mac OS X Dual-boot Using Windows XP Bootstrap

I installed OS X on a separate hard drive. I used the bootloader built into Windows.

The copy the chain0 file from

/usr/standalone/i386/chain0


to

C:\chain0


Then add

C:\chain0="Mac OS X"


To my Windows bootloader (file boot.ini). It works flawlessly. When I turn the computer on, I get a menu for

Windows XP
Mac OS X

I can choose either, and once I select and press enter, it automatically boots into the desired OS. No other settings required.

Hope this helped those who had problem into booting to Mac OS X or finding a software that can dual-boot Windows and Mac OS X. Why get 3rd party, when Windows already have the functionality.

To get more information about chain0, please visit Wiki page on the subject. Also available for download the chain0 file itself.

Running Mac OS X on Intel Pentium IV



Mac OS X



Windows XP


These are expectable screen shot of Mac OS X and Windows XP. (these are not mine, just to show what we can expect to see).

I have tested running Mac OS X on Intel Pentium IV on a partition. This is my experience.

I have formatted and executed Norton PartionMagic 8.05 to partition my hard disk. I have just added a new hard disk, 320GB, making the total space I have 600GB. One partition at 50GB.

Previously, I installed Windows Vista. Though it has good interface, nice to use, but it didn't come to my expectation of easeness to XP likeness. So, I decided to install Windows XP. Having so much problem due to jumper and BIOS settings, I grab Mac OS X and installed onto second partition of first hard disk.

Things went smoothly and the interface was great!

Later, when I tried to install Windows XP and worked, i tried to boot to Mac OS, but I don't know how.

Only a week later, when I decided to search though Google, with this keyword "dual boot windows xp mac os x", I found a website giving instruction, damn easy instruction and using file CHAIN01 and change (by adding single line) in boot.ini that allows me to select Mac OS X boot partition.

So, now I can use both Windows XP and Mac OS X.

Unlike the so many myths online, I am running Mac OS X natively without making any patches. But, still I am having little problems, image file (JPEG, PNG) cannot be viewed using default program and I cannot even play DiVx files. Bad though, because I don't know where to find those program. I am not fluent in Mac OS X.

So, if anyone need helps to install or booting Windows XP and Mac OS X, please post a comment, or contact me and I shall write a simple tutorial here.

Will update "screen capture" (using Nikon camera).


Until then and best wishes.

System Emulator - Qemu

QEMU is a fast processor emulator, written by Fabrice Bellard, which allows full virtualization of a PC system within another one. It is free software. In particular, the QEMU virtual CPU core library is released under the GNU Lesser General Public License (GNU LGPL). Many hardware device emulation sources are released under the BSD license. When running on Windows, the proprietary FMOD library is usually used, which disqualifies it for a single, unified, Open Source software license. QEMU is a hypervisor and is similar to projects such as Bochs, VMware Workstation and PearPC, but has several features these lack, including increased speed on x86 (through an optional accelerator), and support for multiple architectures in-progress. By using dynamic translation it achieves a reasonable speed while being easy to port on new host CPUs.

Qemu Launcher is a Gtk+ front-end for the QEMU, written by Erik Meitner and Linas Žvirblis. Qemu Launcher provides a graphical front-end to all basic, and many advanced QEMU computer emulator options. It allows you to create, save, and run multiple virtual machine configurations, create and convert disk images. Qemu Launcher utilizes the full system emulation mode of QEMU that allows you to run unmodified operating system on virtual hardware. Qemu Launcher also supports launching virtual machines from the command line, by specifying the configuration name. Note that you still need a graphical environment to do this, unless the virtual machine is set to start in non-graphics mode.

I like this program because it has Windows interface, and it can run VMware images. I tried to run Mac OS, but failed. But I am still using this program, interchangably with Bochs.

Rating: 3.8/5.0

QEMU running on Debian Linux. Windows XP is running inside the virtual machine, which in turn is running Internet Explorer 6 displaying the Wikipedia front page.
