Re: FreeDOS and UEFI

The bit about the legacy bios only being activated during the initial boot also rings a bell. I've heard that before too. So even when there is a legacy bios, it might not be there post boot and not support more services than what bootloaders typically use. About ten years ago, I saw a session on F...

Re: Difficulties in DOS on real hardware

Continuing on an earlier thought...all my old hardware is broken, or rotted, or gone by now. So I just don't find any need to write something specific to DOS. Is any manufacturer specifically still making a 386(DX) micro where DOS is the preferred "OS"? I have trouble imagining that such ...

Re: Difficulties in DOS on real hardware

If you want a good emulator to test on, use 86Box or PCem, and emulate a 386DX with MS-DOS 6.22 or the like. Easy to copy files back and forth using ISO images and mounting them as CDs. VirtualBox works better than most (or KVM on Linux) if you have VT-X hardware extensions. I use that on my main d...

Re: Difficulties in DOS on real hardware

Now, I am aware that FB code requires a 386 with an FPU. I have tried WMEMU, however, with no success. So I'm only trying to run the engine on DX processors so far. The only little bit I know about that was shown in the old thread titled "MD5 Calculator" (circa 2009). Apparently, even if ...

Re: Qemu on win7?

If it were me I'd just use VirtualBox and be done with it. It's completely free, and it's faster than Qemu in my opinion (don't think Qemu supports CPU native virtualization). QEMU has virtualization support, but it's usually called KVM there (or QEMU/KVM). Although I'm not sure if the Windows bina...

Re: Watcom debugger with FBC?

I don't remember which version of GDB latest FBC/DOS comes with. I'm on the wrong machine under Linux right now. It's probably something like GDB 6.3. fbc.exe -version ("1.05.0 (1-31-2016)") C:\FB\BIN\DOS\gdb.exe GDB EXE 4,611,584 01-31-16 10:47a gdb.exe --version ("7.7.1") But ...

Re: 32 bit TSR in FreeBasic (yes, it worked, in the end)

I note that you've never have stated just what kind of hardware you wanting to run on. If you want answers to your question about Linux on it, you'll have to provide more details. I'm not the guy asking (but you maybe knew that already): the machines I can get from NCR are 600MHz CPU with 512MB RAM...

Re: 32 bit TSR in FreeBasic (yes, it worked, in the end)

BasLinux fits on two floppies.... and XWOAF fits on a single floppy, and it features a working GUI. Basically, it is as small as KolibriOS BlueFlops (2006?) fits on two floppies and has Links2 and IRC. But all of those are quite ancient. Heck, we have a DJGPP port of Links2 nowadays (and Wget, FTP,...

Re: 32bit TSR

If someone know the best way In dos to copy 20 files extramly quickly (size ranged from 2kb upto 1mb) then I’m all ears (as we say in the UK) Email Eric Auer (FreeDOS contributor) for details, or just ask on the mailing list. He once had an idea (paraphrased) where you seek to the end of the result...

Re: 32bit TSR

perhaps HX DOS-Extender might be of interest https://sourceforge.net/projects/hx-dos/files/ the development is discontinued but it should still be a viable product to use. although it supports multithreading it does not support multitasking, so I doubt that it would work for what you want.

Re: 32 bit TSR in FreeBasic (yes, it worked, in the end)

Maybe I'm a little naive (I never worked with FB-DOS), but wouldn't it be possible to emulate multithreading by periodically switching through multiple segments of the program, each time saving and restoring the set of processor registers? I coded something similar for an AVR microcontroller some y...

Re: 32 bit TSR in FreeBasic (yes, it worked, in the end)

In Linux you can run a standard app (or more than one) in background. And several Linux distributions have the same hardware requirements than DOS with a 32 bit extender (aka the environment you are currently using). Also, I programmed under Linux, and I programmed under DOS, so trust me: programmi...

Re: 32 bit TSR in FreeBasic (yes, it worked, in the end)

... app in the background on Linux, would that be a standard app? Yes, Linux is multitasking, like Windows. DOS fails on that ... (as already many times stated!). You can still buy DR-DOS 7.03 online, but it's a personal license, so you can't redistribute it (proprietary). It does have preemptive m...

Re: 32bit TSR

Yeah, even the "dos ain't dead" forum (http://www.bttr-software.de/forum/) seems to be dead nowadays. It's back now, so try again. BTW, IIRC, the main dude behind CWSDPMI (CWS) had some demo TSR code, but it couldn't be unloaded. So that's not quite ideal, esp. since it ate up a fair bit ...
