freedos beta9 的内核是16位还是32位的?

freedos beta9 的内核是16位还是32位的?

内核是16位的。

听说微软就要推出64位文件操作系统，那么Freedos还有用吗？还有Freedos能否在NTFS操作。

楼上有些朋友说，dos过时了，其实不对的。现在在非常流行的嵌入式系统开发中，dos是用的最多的实时控制系统，此外，还有嵌入式linux，wince，ucos，vxworks（美国军方认证的）等等。16位的dos操作系统在控制系统开发中，字长受限，速度*精度不能发挥到极限。因此，开发32位的dos势在必行。

学DOS已毫无意义，LINUX都没法赶上WINDOWS，强大的WINDOWS，又有谁是他的掘墓者？学用后才觉得无意义。我是从386机玩到现在，在LINUX6.0还可和WINDOWS95匹敌。现在宽带时代，你除非不想看电影、玩网络游戏，只当一名黑客................

要说强大，谁能望商业unix项背。。。除了天文数字般的价格，几乎没有缺点了。
就算苹果的mac系统比起windows也是只强不弱，要知道核心中有很大的bsd成分，也充分说明了复杂繁琐的bsd类系统照样可以做的平易近人。
上面两个在中国的确不怎么流行，但是在外国，市场占有率不比windows差。特别是专业市场，微软只能在性价比上做文章，不断地强调，“俺的东东虽然没unix那么BT,但是便宜啊，大家都来试试。。。”
linux,还用说，万多家厂家不遗余力地发展，大部分工业级强度的软件支持，众多的应用软件，关键是你可以看到源代码，前途一片光明啊。（现在做64位图形工作站，除了sgi自家的IRIX，也就是linux最牛了，windows 64??别开玩笑了，性能和稳定性都差了好多，而且专业驱动也不完备）
DOS，偶印象极为深刻，要知道98年的时候也只有dos下能玩小日本的H游戏啊。。。
在pc平台，dos的确过时了，但是我想每一个学习操作系统原理的人因该最先从这里起步吧，至于实模式的嵌入式系统俺就不清楚了，估计应该前景不错吧。

各位大虾!我听晕了~~~

Wengier ：
你说：“（freedos）支持极大的内存（最大高达4G）等” ，是不是说FREEDOS可以直接管理4G以内的扩展内存呢？它跟MS-DOS有何区别？ 我在WIN98中直接运行FREEDOS的COMMAND.COM 时， 它就占用了74K常规内存， 不知是什么回事？

Oooo understand lar

目前站內提供的DOS下載都是免版權的嗎？"它们都是自由（free--libertarian）的，而不是免费（白送，gratis）的"那又該向哪購得？

什么DOS好用啊

FreeDOS
Master HDD Image Creation Instructions
v. 0.3
Build 44APfdBNR1
Setup:

Before starting:

A. Flash to the latest released BIOSB. Tattoo the system and the Channel field to “LX”Load BIOS Setup Defaults and Save Settings
Boot back into the BIOS and verify PNPOS is set to “No”C. If you’re planning using a Grantsdale system to create the FreeDOS image:During BIOS post press <F11>.Verify that in the BIOS’s “Advanced” section that the “Onboard PATA/SATA Configuration setting” is set to “Combined Mode”, the default is “Enhanced Mode”.If you don’t do this you may not be able 1. To boot to the CD-ROM devices using the SystemResourceCD2. and/or you may not see your Fat32 partitions that were created in FreeDOSNote: All FreeDOS Grantsdale systems will be shipped with “Enhanced Mode” as default.

What You’ll Need:

FreeDOS beta 9 ISO: downloaded and burned to CD (1)This will be used for creating the Fat32 Image only!SystemResouceCD ISO: downloaded and burned to CD (2)myimage.000 file (FreeDOS HDD Image): downloaded and burned to a CD (3):This file must be burn onto a disk in a single session. Do not use a disc that has multiple sessions, because Linux may not be able to read it.
A system with 2 CD-ROM drives and 1 Master HDD
Note: You MAY need to create a separate Master HDD Image for
1. EACH HDD configuration
A. PATAVersus
B. SATA2. And for EACH HDD size

Note: RAID – Imaging process with RAID not yet supported with FreeDOS
Under investigation

Creating the FreeDOS Master HDD:


Part I:
Creating the Fat32 Partition using FreeDOS beta 9

Turn on the PC and insert the FreeDOS Beta 9.0 CD into the CD drive.
Turn off the PC.
Turn on the PC. The computer boots from the FreeDOS CD.

At the FreeDOS splash screen, (Warning: HD boots in 15 seconds!)
Enter: 1 and press <Enter>

Select 2) Boot without XMS attempt cdrom loading
Enter: 2

Select 1) Configure FreeDOS installation settings
Enter: 1

This next screen will only come up if the HDD already has partitions
Select 1) Start installation of FreeDOS beta9
Enter: 1

Press any key at “THE FREEDOS BETA 9 DISTRIBUTION” page.

Press <Esc> to exit out of the FreeDOS DETAILED INSTALLATION INSTRUCTIONS page

Select 1) Partition harddisk using fdisk
Enter: 1

You should be familiar with the next screens – Same as MS-DOS

Do you want to use large disk [Fat32] support {Y/N} [Y]
Press <Enter> for Yes

For Unpartitioned HDDs, skip down to “Create a Primary Fat32 FreeDOS Partition”

For HDD previously partitioned for other OS’s, first

View the Partition information
At the “Choose one of the following:” prompt
Select 4. Display partition information
Enter: 4 and press <Enter>
Note all partitions (if any) that are present (Primary, Extended, Logical, Non-DOS/NTFS), because you will need to delete them all.
When done, press <Esc>

Delete all partitions
At the “Choose one of the following:” prompt
Select 3. Delete partition or Logical DOS Drive
Enter: 3 and press <Enter>
Delete any Primary, Extended, Logical, Non-DOS/NTFS partitions

Create a Primary Fat32 FreeDOS Partition
At the “Choose one of the following:” prompt
Select 1. Create DOS partition or Logical DOS Drive
Enter: 1 and press <Enter>
Select 1. Create Primary DOS Partition
Enter: 1 and press <Enter>

When prompted,
”Do you wish to use the maximum available size for a Primary DOS Partition and make the partition active (Y/N)….? [Y]
Press <Enter> for Yes

When “Primary DOS Partition created” message appears, press <Esc>
Press <Esc> again and then TURN OFF the system at the prompt:
System will now restart
Press any key when ready…

Part II:
Imaging the FreeDOS image (myimage.000) onto the HDD using the SystemResourceCD
Turn on the system and remove the FreeDOS beta 9 CD.
Insert the SystemResourceCD (CD 2) into the top CD-ROM drive
Insert the myimage.000 CD (CD 3) into the bottom CD-ROM drive
Turn off the system

Turn on the system and boot to the SystemResourceCD
At the “Enter to boot:” prompt, press <Enter>

Keymap selection:
Enter: 41 for “us” and press <Enter>

You should be booted to the Linux command prompt of the SystemResourceCD if everything went fine.

Linux Virtual Console # 1/6
root@cdimage /root %

Mounting the second CD-ROM drive:

At the prompt enter:
root@cdimage /root % mkdir /mnt/mydir
root@cdimage /root % mount –t iso9660 /dev/hdd /mnt/mydir
root@cdimage /root % cd /mnt/mydir
root@cdimage /root % partimage

Partition Imaging Utility: PartImage 0.6.4
Identifying the correct Partition information before continuing:
If the “Partition to save/restore” section reports
“ide/host0/bus0/target0/lun0/part1 -unknown- [HDD size] ” this is correct.
Verify the HDD size is also correct.

However, if your drive has either
1. No partition defined
2. More than 1 partition defined

Repeat Part I: Creating the Fat32 Partition using FreeDOS beta 9

There must be ONLY 1 Fat32 Partition defined.
Having more than 1 partition defined or no partition defined will lead to improper results.
E.g. You will either be
A. Booted back out of the partimage program (No partition defined)
B. Or the system will not be able to boot from the HDD image when imaging is complete. (Occurs when installing the FreeDOS image to a non-active partition)

Using the Partition Imaging Utility:

Press <Tab>
In the “Image file to create/use” box
Enter: myimage.000
Press <Tab>
Press the down arrow to select “Restore partition from an image file” and
Press the <Spacebar> to select this option.
Press <F5> to Continue
At the “freedos [OK]”,
Press [OK]
Press <F5> to Continue
FAT information page
Press [OK]
Confirmation page
Press [YES]
It should take 5-6 seconds to image an IDE HDD
It should take 15-16 seconds to image a SATA HDD
At Click [OK], press [OK]
You should be booted out of the partimage program at this point
At the prompt, enter: halt –n
The systems should shut down automatically
For Grantsdale systems only: the system will not shut down automatically.
Turn off the system, when this last line appears
“Remounting remaining filesystems read only…”


Booting your FreeDOS Master HDD
Turn on the PC
Eject both CD-ROM drives and remove the media
Verify the system boots completely to the FreeDOS kernel version 1.1.32…
The last line should read:

“Select from Menu [012345678], or press [ENTER] – Singlestepping (F8) is: OFF

Turn off the system
Turn on the system
Verify the system boots completely to the FreeDOS kernel version 1.1.32…
Turn off the system

This will be the MASTER IMAGE that the factory should clone.

Label the MASTER IMAGE with the name of the motherboard it was created on.

Create submasters and test the image before replicating the MASTER IMAGE.

REPEAT THIS ENTIRE DOCUMENT FOR THE NEXT SKU/MOTHERBOARD configuration.
