China DOS Union

It should be the x86 architecture, and the system running on it is Windows Server 2003 (32bit). However, with 8GB of memory, less than 4GB can be used, and the remaining 4GB belongs to the PAE range.

I have only used 9.55 and 9.57, just haven't used 9.56, and haven't tested with a hard drive exceeding 250G. Some say it's okay, some say it's not.

Anyway, the compatibility of the 9.xx versions with large hard drives is indeed not good. It is said that there is a new one recently, but I haven't used it and don't know clearly.
Now, hard drives larger than 250G, 320G, have become mainstream. There are also many SATA hard drives. Some motherboards still can't use IDE compatibility mode, and some old partition software is no longer up to the task. The capacity of hard drives is getting closer to 2T. With the breakthrough of 2T, many old systems and old software may be eliminated, especially old partition software.

From the current situation, if the 2TB barrier is broken and GPT partition tables are used, it's not just old systems and old software that will be eliminated. None of the commonly used current partitioning software supports the GUID partition table, and currently, only Windows based on IA-64 or EFI x64 can boot from a GPT hard drive. Therefore, to support hard drives larger than 2TB, even BIOS and 32-bit Windows versions may need to be eliminated, and incidentally, 16-bit DOS will also lose the BIOS environment it relies on.

Perhaps the 2TB hard drive threshold may cause significant changes in PC machines, with EFI and 64-bit operating systems becoming dominant.

Hehe, this post is interesting, and as we talk, we get to the development of the entire PC. Taking this opportunity, I also talk about my thoughts all the time. Simply put: sometimes I think do we really need such a large hard drive? Of course, "we" here refers to ordinary PC home users or computer enthusiasts. What do we have in these hard drives? I see that most of the space occupied are just some data, more specifically, just some files like movies, songs, pictures, etc. Do these things need to stay there all the time? I don't know if you guys delete all these things and then look at how much space your software, including games, actually needs. I don't know what the largest game's space requirement is currently, but dozens of GB is enough. Actually, if these data files really need to be preserved for a long time, just burn them to a CD. You can take them out and watch them when you want. A movie, no matter how classic it is, you won't watch it several times a day.

So, I always think that everything has a limit or step of development. When it reaches a certain level, it's difficult or unnecessary to develop further. For example, cars on land, including cars designed for racing or breaking records, reach a certain speed and are almost there. Going faster would make them almost ground-effect planes, which have no practicality; warships in the sea, after hundreds of years of development, are generally around 30 knots now. Of course, they can go faster, but it's not worth it (except for small warships). Of course, this refers to traditional displacement ships. For non-traditional ships like air cushion ships, wing-in-ground effect ships, it's the same. In fact, wing-in-ground effect ships can be approximately regarded as ground-effect planes; the same goes for airplanes. Traditional propeller planes have a maximum speed of about 1000 km, traditional jet planes have about 2M, and if you go higher, the engine needs to be replaced.

By the same token, for PCs, will we really require unlimited capacity? Initially, the rapid development of PCs was because the performance at that time couldn't meet people's needs. When it reaches a certain level, I think there's no need to develop further. You see, now you can buy any PC and it can meet daily needs. Of course, things are always developing continuously. The emergence of new things doesn't necessarily immediately eliminate old things, because old things have their own advantages. For example, when you travel, taking a train, of course, a steam train is good. You can have a slow meal while enjoying the scenery with the "突突突" sound. It's said there's such a place in Scotland, and I really want to go if I get the chance...

I am fortunate to take the lead in offering a simple example! Hehe!

In fact, the simplest and most effective way to partition is to use the XP Recovery Console, which has the highest compatibility. As for RAID controller and SCSI support, as long as you add the driver in the installation disc before making the Recovery Console, the made Recovery Console will support accordingly.

I actually hope the harder drive is as large as possible. My current 160G hard drive is almost full, and many things can't be burned to discs, mainly software CDs or hard drive images. Besides, discs are too unstable and slow. I can't even guarantee how many times a burned CD will work now.

Now the hard drive capacity is getting larger and larger, and the price is getting cheaper and cheaper, but the quality is much worse than before.
I just broke a 250GB hard drive these two days, fortunately, all the data was recovered.

Now it seems that no storage medium is reassuring, and I even have a phobia of data loss now. But the floppy disks I had more than ten years ago can still be read, heh heh.

Software CDs are originally CDs, and they can be burned unless they are encrypted. As for the hard disk image, it's not important anyway, and it can be redone. The key is to back up some classic software and personal data.

Relatively speaking, RAID5 is still more reassuring.

I'm used to using a virtual CD-ROM to directly open software discs for use. I've said it before, discs take a long time to burn and read, and they're not reliable. It feels that hard drives are more reliable. But if you really encounter a hard drive that breaks in a few days, it can only be said to be bad luck. Also, my experience is: ensuring the quality of the power supply is very beneficial to the lifespan of the hard drive. For example, connect an online UPS to the machine. Another experience is: make multiple backups of important data. Also refer to the processing principles of DOSForever, and burn and keep those things that are not very useful.

That's amazing, you can even set up a server, I admire it.

Can see the end, it seems the owner's problem hasn't been solved yet, is this thread meaningful??

The problem is solved. I mass-produced a CD version of the system disk and can perform a series of operations below! Thank you everyone! The CD can effectively solve the SATA problem! DM can also be used!

As long as the BIOS supports it, DM957 supports hard drives larger than 120GB, but I don't know if it can support hard drives larger than 320GB.
