If you take the terms VGA, EGA, and CGA, and MCGA literally, well.....

3 Upvotes

All these adapters had color graphics (CGA).

All these adapters were some enhancement over monochrome (EGA)

All these adapters consisted of video of graphics from some array (VGA)

All of these adapters had multiple colors (MCGA)

And, all of them were an adapter which relied on some array for graphics. Sometimes the A stood for either adapter (like in CGA and EGA), or stood for array (like in VGA).

Games from the CGA, EGA, MCGA, and VGA eras were all great DOS classics, and well, all those terms would be used interchangeably if we took them all literally.

Now, here's a chart for their official meanings, as opposed to what they can be literally described as.

How to use DOS to limit internet access

0 Upvotes

Hey guys, I tried to post this over in r/powershell but the mods removed it after it gained traction. I don't know where else to ask this, so even if it does not fit this subreddit do please direct me to an appropriate place.

Okay, with that out of the way.

I am trying to limit internet on my maching from 8AM to 12PM via powershell. I used GPT to help.

So here are some commands that work

To create internet kill switch on laptop:

netsh advfirewall firewall add rule name="InternetKillSwitch" dir=out action=block protocol=any

To kill internet on laptop (test to show that it work)

netsh advfirewall firewall set rule name="InternetKillSwitch" new enable=yes

To enable internet on laptop (test to show that it works)

netsh advfirewall firewall set rule name="InternetKillSwitch" new enable=no

However, the following does not work. I assume that it doesn't work when the machine is off.

To UNblock internet at 8:00AM, task called "EnableInternet"

schtasks /create /sc daily /st 08:00 /ru SYSTEM /rl HIGHEST /tn "EnableInternet" /tr "powershell -command \"netsh advfirewall firewall set rule name='InternetKillSwitch' new enable=no\""

I tried to edit it so that it checks the time every minute. That way if the machine is turned on AFTER 8AM, it works. But the following does NOT work

schtasks /create /sc daily /st 08:00 /ru SYSTEM /rl HIGHEST /tn "EnableInternet" /tr "powershell -command \"netsh advfirewall firewall set rule name='InternetKillSwitch' new enable=no\"" /ri 1 /du 24:00

Any help would be much appreciated!

Is there a REDDIT community that deals with Windows commands as used in BAT files (similar to a the Reddit Powershell community)? I searched but can't find one. Is there a master directory of all REDDIT communities I can search through?

MS DOS Expert needed!

1 Upvotes

Hello there,

I recently got all nostalgic and wanted to play the classic Prince of Persia DOS game and after 45 minutes of game play I died and had to reboot from the beginning (without anyway of saving or creating a checkpoint) but then I remembered that my old computer mentor from my child hood in the 90s had found a way to start the game directly to any level she wanted to.

I went through rummaging through the internet forums to figure out how she did that and I couldn't, I tried checking if there are parameters that I can pass to the .exe file or open and modify the DAT files etc.

It would help me solve a great mystery on how to start the game in the level I want to plus finish the game actually

You can find the game at : Prince of Persia

Favorite DOS Screensavers

3 Upvotes

What were your favorite DOS screensavers from back in the day? I am looking for some screensaver apps that work in DOSBox Pure which means that I don't want any that have to edit registry files. I do know about After Dark, but that application does require changing the registry files. I am also 100% okay with NSFW screensavers too. What screensaver apps would you recommend? Thanks in advance.

Various eras of DOS

0 Upvotes

The DOS era, as an era, lasted from the 1970s, to the year 2000, at least to a mainstream level. But the DOS era lives on unofficially as well, through DOSBox and FreeDOS, now, let's explain the sub-eras of DOS.

CP/M Era:

CP/M Came out in the 1970s, and it would be a precursor to DOS with some similarities.

IBM PC Era:

started in 1981, and the PC would use BASIC as its original OS, for the original model. Then PC DOS came out the same year

Windows Era:

The first version of Windows came out in 1985. It started off as a GUI that ran on top of DOS, long before any later version would entirely replace DOS for the mainstream.

MS-DOS Era:

The first version of DOS using "MS-DOS" as a trademark came out in 1987, and MS-DOS would have many versions, at a technical standpoint.

If the phrase "Microsoft DOS" is taken literally (sorta), well, PC-DOS was also developed by Microsoft.

Windows 3.0 Era:

Windows 3.0 would be a version of Windows which would be more consumer friendly than previous versions of Windows, and also ran on top of DOS, and would be a precursor to future Windows versions.

Version 5.0 Era:

version 5.0 of MS-DOS would be the first retail upgrade for MS-DOS, and would also be the oldest version of DOS to run the newest programs made for DOS if you exclude Windows 9x/Win32.

Windows NT Era:

Windows NT first came out in 1993, and would deviate away from using DOS as OS to run on top of, but yet, had code to emulate MS-DOS to run some DOS applications.

Windows 9x Era:

Windows 95 first came out in 1995. It would use DOS as a bootloader, and have 32-bit applications. It had "DOS Mode" for running applications which had issues running during normal Windows 95 operating mode, and would also offer LFN (long filename) support for FAT and FAT32 file systems.

Windows 98 would come out a few years later and be sorta "Windows 95 with more enhancements".

New Millennium Era:

During the new millennium, circa 2000, which many called "Y2K", two products, Windows 2000, and Windows Me would come out.

While Windows 2000 would be a later version of Windows NT that would boot as a nearly stand-alone OS but had provisions to run DOS programs on top of it.

While, Windows Me on the other hand would also use DOS as a bootloader like Windows 95 & Windows 98 would, so Windows Me was still part of the "9x" lineage in technical ways.

Windows Me would also be the final version of MS-DOS, but for technical reasons.

Post-DOS Era

The Post-DOS era would be an era when DOS would no longer be a bootloader for future official Windows versions, and Microsoft stopped releasing official versions of MS-DOS after that.

Windows XP would mark the beginning of a Windows without DOS, in the bootloader context, as XP would also be the first consumer version of Windows NT.

However, Windows XP still had accommodations for running DOS programs via emulation of some kind.

DOSBox Era:

Started circa 2005, when the first version of DOSBox came out.

From here, old DOS programs would start to live on through emulation, in a more independent way than NT's NTVDM system, as Microsoft was slowly phasing out DOS support for it's future versions of Windows.

64-bit Era:

When 64-bit systems first came out, namely Intel's Itanium processors, this would be an era when Intel would deviate away from the x86 architecture, and special versions of Windows XP would omit DOS support.

x86-64 Era:

starting circa 2005, a 64-bit version of Windows XP using a 64-bit version of x64, namely AMD's AMD64 processors, would leave out DOS support, and support for 16-bit Windows 3.x era apps, to where one had to install DOSBox, or simply a 32-bit version of Windows instead.

future versions of Windows would start to have 64-bit versions.

Windows 11 Era:

Windows 11, came out circa 2022, would mark the end of Windows having 32-bit versions, which in turn, marked the end of DOS support altogether, as Windows 11 will only have 64-bit versions.

but one can install DOSBox on this version to work around that.

Future

Even though MS-DOS has been removed from official Microsoft products entirely, even just as a compatibility layer feature of Windows, it will live on through emulation on DOSBox.

People will still make homebrew EXE files using the (will sound technical) MZ header, similar to how homebrew ROMs for NES and Sega Genesis are made for console emulators.

but what does the future hold? well, it will be explained in the history of computers, but will it be discussed in school history class? I hope so.


Just thought I'd share a generalized sub-era timeline for DOS's lineage of OS and emulator products.
