Installing MS-DOS on a Dell Latitude D620

[weberdarren97]

Hello all,
I have an old Dell Latitude D620 laptop... I have been using DOSBox to emulate DOS on my PC and I want to free up said memory on my desktop and install DOS on my laptop.

I was going to use MS-DOS 6.22. I can get it from here.

I have a few questions...

1. Can DOS run on a motherboard this new?

2. Can DOS take advantage of the full clock speed of an Intel Core Duo T2500?

3. Can DOS take advantage of all 4GB of DDR2?

4. Can DOS use SATA drives?

5. Can DOS use USB flash drives? I'm not even going to try USB 3.x.

6. If the answers to the above questions are no, is there any magic I can do in BIOS to make it more compatible?

Hi

Msdos limitations
640 meg of ram usable
But expanded memory manager can use extended memory beyond 1 GB

Suports hard disks formated fat 16 eg 2GB partitions and maximum 3 primary + 1 extended one which can have multiple 2 GB partitions

Providing sata controller can be set to ata compatible hard disk access should work

Msdos 6.xx has not been developed for about 20 years

Free dos is still available as freeware and has drivers for more modern hardware
Including usb ports

It is fairly compatible with msdos programs
You can get a iso image and install from a cd to hdd

Msdos requires a bootable floppy disk drive to be able to install on a hard drive

What about a virtual pc running msdos or free dos on the laptop instead
much less hard work involved in configuring the config.sys and autoexec.bat files

Sorry i have not included link to free dos download
You should be able to find it using Google

Choose your favorite free virtual PC
