I am using MS 4.0 and CodeView on an NCR PC-8 (AT Compatable) with a Video-7 Vega EGA card. My problem is that whenever I start CodeView it turns the screen pink and green. Does anyone know how I can make it just come up in normal colors? The manual was no help at all. -- Michael Lodman Advanced Development NCR Corporation E&M San Diego mike.lodman@SanDiego.NCR.COM {sdcsvax,cbatt,dcdwest,nosc.ARPA,ihnp4}!ncr-sd!lodman

The other thing I don't like about CodeView is that it flips into the output screen as the default when you are tracing through code. Is there a way to make not flipping to the output screen the default? By the way, the patch for the pink and green screen works great! -- Michael Lodman Advanced Development NCR Corporation E&M San Diego mike.lodman@SanDiego.NCR.COM {sdcsvax,cbatt,dcdwest,nosc.ARPA,ihnp4}!ncr-sd!lodman

MicroSoft was coding around some "undocumented features" (read bugs) on IBM's EGA, and inadvertently broke it on non-IBM cards. Anyway, they have a free patch to CodeView that fixes this. You can call their 800- number to find out how to get the patch. In general, MicroSoft has a bad reputation for only testing their code on IBM hardware. As another example, Windows attempts to detect the presence of an EGA card by looking for the string "IBM" in a fixed location in the EGA BIOS. (And this is in spite of the fact that they developed Windows using Tandy 2000s!) -- {hplabs,amdahl,3comvax}!bnrmtv!perkins --Henry Perkins It is better never to have been born.

The manual was no help at all. > -- > Michael Lodman The problem is that codeview loads fonts and re-calcs the screen and then sets the pallet which apperently gets screwed up. So here is the fix. The following is a debug session to fix the problem. Be sure to save a copy of codeview somewhere else incase things get screwed up. C>RENAME CV.EXE CV /* this causes the debugger to load as image */ C>DEBUG CV -D DS:3241 L2 <ret> CD 10 /* if you don't get CD 10 here then see below */ -E DS:3241 <ret> CD:90 <ret> /* change the call to a NOP */ 10:90 <ret> /* change the interupt number 10 to a NOP */ -D DS:3280 L2 <ret> CD 10 /* if you don't get CD 10 here then see below */ -E DS:3280 <ret> CD:90 <ret> 10:90 <ret> -W <ret> /* write file out */ -Q <ret> /* exit debugger */ C>RENAME CV CV.EXE Run it and see if it works. IF YOU DON'T FIND THE "CD 10" TRY THIS -S DS:0000 FFFE B8 02 10 CD 10 This will search for all the interrupt 10 calls that cause the problem, NOP theses out like I show you above. -- Jack Hudler, Computer Support Corporation, Carrollton,Texas 75006 (214)661-8960

CodeView also does really wierd color things to my display if I try to run it in 43 line mode. I figured it was a problem with the monitor, but maybe CodeView is doing strange things... -- ...!hplabs!sdcrdcf!trwrb!orion!heins We are a way for the universe to know itself. -- Carl Sagan

MSC CodeView, as distributed with MSC 4.0 works just fine on a Samsung S-286 with a Samsung monitor, Paradise Auto-switch card, and a Mouse Systems Mouse. I ALWAYS use it in 43-line mode. When in doubt, suspect the EGA (:-); I borrowed a Video-7, and it behaves just like Michael said it would, unless I ran EGApaint first and mucked with the color maps.

Distribution: We have a whole lot of Everex AT clones, including their clone ega card which uses the Chips and Tech. chip set. There is a problem with CodeView and, although it works fine on the IBM ega, it has caused problems on all our clones that use the C&T set. MS has a fix and shipped it too me within days of calling them. I'd post it, but MS might not like that. Its a real short debug script. Give them a call. My system now works just fine. steven tektronix!gvgpsas: s: s
