I'm not sure CONFIG.SYS' "screen=" itself supports many modes, probably only three or four. http://www.freedos.org/kernel/config.txt That says this: " SCREEN Usage: screen=xx Switches into videomode xxx (INT10/11xx/000) where xx should be 0x11 for 28 lines or 0x12 for 43/50 (EGA/VGA) lines " AFAIK, technically speaking, for DOS you can only go up to 132x60 with VESA. I don't know about plain VGA, probably 80x50. FD MODE may indeed be limited in functionality, but it's still possible (I guess?) to use other modes with outside tools. Well, I don't remember trying much, and I wasn't impressed with the results of some higher-mode VESA tools. Quite honestly, I find 80x43 plenty good enough these days, at least with this particular (old) monitor. Lemme post a few links to some tools that you can try, if you're bored. But keep in mind that a lot of other, older DOS tools in general aren't very compatible and either won't support such modes fully or will crash. In particular, text editors are usually notoriously bad about that. 1). http://www.japheth.de/Download/DOS/SETMXX.zip (supports VGA: 80x34, 80x60; VESA: 100x37, 128x48) 2). http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/util/user/svgatextmode_1_9_16rc1-dos.tgz (Untested by me, but be careful not to try anything higher than your card supports.) 3). http://omniplex.om.funpic.de/dos/setlines.htm This claims to support a lot, including 132x60, which it calls "VESA mode 10C, 8 x 8 default". > by the way, http://help.fdos.org/doc/mode/mode.txt is a 404 error, and the > documentation (maybe just paste from mode output?) is incomplete. You can still download and read HTMLhelp offline, of course: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/dos/help/ But I think the link you're looking is here (and still works): http://help.fdos.org/en/hhstndrd/base/mode.htm Hmmm, that seems to imply 132x60 is supported, so dunno why that wouldn't work for you. Though I doubt you'd find that pleasant to read, but YMMV. :-) > is there some way I can get an update to mode that can do this? if it > already does, then maybe it's my video card BIOS(?). Patches welcome! :-) No, seriously, it hasn't been updated since 2005, and although Eric Auer is still around (but often busy), I'm not sure he's majorly interested in fixing it. Though the online .LSM still lists him as "Maintainer", so I guess he's legally obligated! ;-) j/k Preferably you can just use some of the aforementioned third-party utils to do what you want (or at least similar). Though, again, even if the mode is supported for your card + monitor, it may not look how you want, and other tools may not handle it properly. > none of the screen= modes does 132 columns.

Can't remember, probably never tried, don't do lots of VESA work, sorry. But it shouldn't be hard to find out. http://en.wikipedia.org/wiki/Vesa http://en.wikipedia.org/wiki/VESA_BIOS_Extensions ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
