Re: [Freedos-user] I want to port drivewire to freedos...
O.K. It looks like it depends at least on pthreads, curses, termios, and linux-specific tty devices. Often (as is the case with curses), linux C libraries are available under FreeDOS with DJGPP; they are the same libraries, just re-compiled (DJGPP has a fairly POSIX-compatible c-library, it is somewhat comparable to cygwin on Windows.. Curses is easy, pdcurses is available for 16-bit or 32-bit DOS. Also ncurses is available for DJGPP. If you plan on implementing it with GEM, you would likely want to replace the parts that depend on curses with GEM-equivalent functions (curses does all of the screen-manipulation). If you plan on a 32-bit port (GEM has djgpp bindings IIRC), termios is available in the c-library to manipulate the screen and also there are pthreads libraries available for djgpp. But if termios is used to manipulate the serial ports as well, you would need to implement a file-system extention (see http://www.delorie.com/djgpp/doc/libc/libc_321.html for a description) to handle serial devices as well as screen devices (and maybe also create your own termios interface to serial ports). The file-system extention would probably suffice to access linux-specific tty devices. If you plan on a 16-bit port, pthreads (a multi-threading library), would be a challenge to implement (but likely possible), and termios would be possible to implement, but I don't think there exists a termios-compatible library for 16-bit DOS. termios probably wouldn't be too difficult to implement for 16-bit DOS. Accesses to linux-specific tty devies would have to be replaced with DOS-equivalent functionality. Overall, it's a decently-sized job. Plus if you don't know how to write GEM applications, you would have to learn that as well. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Re: [Freedos-user] unload previsiously loaded exe and sys on fdconfig.sys
Hi Michael, Do BIOS update 100 % step by step as the manual says. No experiments wit h DOS versions, TSR's, boot medium (if you shall use legacy floppy then do so). Otherwise you risk the BIOS update to fail as the developers did not thought about your modified use. I agree that unloading TSRs can cause risks, but I would not overdo the 100% step by step part. Remember that even big mainboard makers shipped half-broken modifications of FreeDOS with their products and that for example MS DOS simply is no longer legally available for normal post-Win9x home users. Ok, well you can experiment if you have the equipment to remove the flash chip and to flash it from outside. Better BIOSes have various fallback options, such as a second copy of the BIOS or a part which cannot be flashed which is able to load update floppies even after a failed BIOS update. I personally would say that floppy is best (if you still have a drive) followed by harddisk, CD/DVD and then USB. You should avoid loading EMM386 for compatibility reasons but HIMEM should be safe for most BIOS update tools as far as I remember... If your BIOS USB drivers are not stable, it might help to copy all relevant files to RAMDISK before updating the BIOS. You could even BOOT from a RAMDISK, using ISOLINUX / SYSLINUX and MEMDISK. In general, it is bad if you have to load fancy drivers such as USB, NTFS or network, between booting and flashing... It is much better if you can put your BIOS update files directly on the drive where you will boot from, so you need no extra driver.

Hi Robert, Shane, Ben Armstrong (a Program manager on the core virtualization team at Microsoft) recommends the following for MS-DOS on http://blogs.msdn.com/virtual_pc_guy/archive/2004/10/21/246136.aspx Note that this is from 2004 so it cannot be about Virtual PC 2007 ;-) device=C:\DOS\EMM386.EXE RAM I=B100-B7FF I=C600-C7FF Re-using part of mono text buffer (B100-B7FF) and part of a typical VGA BIOS area (C600-C7FF) sounds a bit desperate if you ask me... Modern EMM386 such as the JEMM386 from www.japheth.de that you recommended also auto-detect the size of the VGA BIOS anyway :-). I=CC00-CFFF I=E600-EFFF FRAME=d000 This is odd - Shane Baggs suggested quite different options on 11 March: I'm running it on Virtual PC 2007 under Windows XP on a laptop with a Pentium M. It crashed at first, but it's now solid as a rock with this line in FDCONFIG.SYS: DEVICE=C:\FDOS\BIN\JEMM386\JEMM386.EXE NOEMS X=CC00-CFFF NOINVLPG ... NOEMS is optional. With NOEMS, no page frame is allocated (it could start at D000 or later, up to E000). This gives you 64 kB more UMB but old EMS 3.2 software will be unhappy. EMS 4.0 compatible software stays happy. NOINVLPG was written by Japheth specifically for [Virtual PC] Note that classic FreeDOS EMM386 is outdated but probably did not use INVLPG anyway so you need no specifically-made- for-Virtual-PC option to fix VPC compatibility either ;-). The X=CC00-CFFF was arrived at through testing by trial and error. So Shane suggests to EXCLUDE CC00-CFFF while Ben suggested to INCLUDE CC00-CFFF (and D000-DFFF and E600-EFFF...) That gives me the idea that Ben wants to say that you should exclude E000-E5FF instead of CC00-CFFF for Virtual PC of the year 2004. Can somebody who has Virtual PC 2007 have a look at memory contents and about the effects of... X=cc00-cfff versus X=e000-e5ff ...on the stability of FreeDOS with EMM386 / JEMM386? Thanks! I have the following IDEA: Maybe the X=cc00-cfff, while NOT using the NOEMS option, had an influence on where the EMS page frame was, pushing it at the bad area - and pushing UMB area away from it. Because EMS is less often used than UMB, you still get fewer crashes if the bad area is only in use while EMS is accessed... You can use MEM or Quarterdeck MFT / Manifest to see where EMS page frame and UMBs are :-). Shane, could you post some relevant parts of MEM /D and MEM /E output with and without X=cc00-cfff combined with with/without NOEMS option along with information which of those 2 * 2 config possibilities are stable and which are not?

Re: [Freedos-user] FreeDOS on Virtual PC 2007

When I read the batch file in FreeDOS the file is full of gibberish. In Notepad on my WinXP machine, however, it is a properly formatted text file. Another detail that might have a bearing: the physical floppy disk is being read by a SuperDisk drive instead of a standard floppy drive. I know that floppies formatted using this drive aren't readable by normal floppy drives (SuperDisk drives however can read normal formatted floppies just fine). Maybe this is the source of the problem? If so, can anyone recommend software to create floppy images without needing an actual floppy drive? Thanks! -Mike -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
