Hi guys, >> I just need to figure out the best way to network...
>> FreeDos starts so fast I might try transferring to a qemu image... If you ask me, it is easiest to copy the files to your target disk while it is connected directly to Linux. As you are interested in small computers, you might be using USB, SD, CF or MicroSD anyway. If you use network, you would have to take care to have drivers for your network card for DOS, which is tricky for new chipsets. You can also dual-boot and simply put DOS and Linux on the target disk and then boot your computer to Linux when you want to do internet stuff. > it's things like DPMI which are complex as all hell. Which is why compilers like DJGPP make sure that you barely have to use DPMI explicitly. Common interaction with the DOS kernel as file I/O is handled by your C library there, so you do not have to worry about how to transfer data between 16-bit "real" mode DOS and 32-bit protected mode DJGPP program. If you look at for example the DOSFSCK port, you will see that at most some rather specific interrupt calls needed any explicit DPMI related action. If you want more than 640k RAM the easy way, protected mode compilers such as DJGPP are really useful. There will be a moment for learning how to do fast graphics (VGA, VESA, VBE, test...) I/O in protected mode, but you can check existing examples. If you only care for speed-uncritical text mode, just let DOS or BIOS handle the I/O, which is automatically wrapped for protected versus "real" mode interfacing by the DJGPP libraries. If you totally love the old DOS compilers and still need more than 640k RAM, you will have to learn how to use EMS or XMS to page or copy small areas of your large memory allocations to/from the small DOS world. In any case, I do NOT describe it as world of hurt :-p Will be away from DOS for a few days, have fun :-) Eric ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
