GRUB question 2254

Note: I hope you are not testing this on a modern computer - 64bit+dual core, it will not work. I recently tested, Dos, Freedos, and MS-Windows-9x on modern college computers, results are not very good. As long as you have 32bit, Pentium II-III - you should be okay. I posted my finding, in this NG, and I hope other users will let us know if there is any error in my test.

Sorry typo it's (hd0,0), I have two parbreastions :)

This is what I have in my menu.lst

################## breastle Windows 95b - Dos root (hd0,0) savedefault makeactive chainloader +1 ##################

True. "root (hd0,0) =dev-hda1"

You need to know what MBR is.

"Short for Master Boot Record, a small program that is executed when a computer boots up. Typically, the MBR resides on the first sector of the hard disk. The program begins the boot process by looking up the parbreastion table to determine which parbreastion to use for booting. It then transfers program control to the boot sector of that parbreastion, which continues the boot process. In DOS and Windows systems, you can create the MBR with the FDISKMBR command."

Think of it like a president, or king. It is above parbreastions. It sits in "first sector" of the hard disk".

Don't worry about it

Oh, it much more then that. You see 'sys' command create "io.sys, msdos.sys, and command.com" which will work on a specific hardware. Program scan a computer, and write made system files compatible on a scanned computer, or floppy disk. Think of it like this; you go to a tailor, he needs measure you before he can make a suit for you. 'sys' is measuring your computer, and making a dress for your system "io.sys, msdos.sys, and command.com"

Yes - then mount it, and test it.

I learn something new about this: when I was testing dos in AMD computer, I had to reformatdev-hda using freedos. However, this was not the case with MS-DOS.

Right

2-5 are wrong

What I was trying say is: when you boot DOS from CD-ROM, a virtual drive A: will be created. If you have a floppy disk drive on your computer, use the letter B: for the VFD floppy disk drive. If you DO NOT have a floppy disk drive, use the letter "A:" for VFD.

Okay, very simple.

Reboot the computer.

Use bootable CD. Find the dos command "sys"

once you have found - type - "sys a: c:" It will say something like "system file have been transfered". You are successful

Reboot it again, and select "dos" from grub, and that's it.

Now the bad new: I tested dos on five computers. I found out that Dos doesn't work well on modern computers, specially AMID 64bitdual core. You would need to remove everything, even reducing rams, video cards, and lot of other stuff.

Main issues are with

SATA-II Hard drives USB 2.0 (1.1 is okay) AGP-PCIx Video cards LCD Monitors DVI & Wide-scareen. Color Laster printers.

Infact Windows XP has a problem with SATA-II (see the link)

As I mention above - I have asked other users - if there is anything wrong with my finding. Unfortunately, DOS days are numbered, and Windows XP is not far behind.

Ps: When professor saw me doing this - he gave me part-time job in the college :)
