I am running pure DOS 7 from Windows 98 US, no drivers, no TSR programs. Just COMMAND.COM, no AUTOEXEC.BAT and CONFIG.SYS.
Run CWSDPMI -p -x DPMI stays in memory, start FP.EXE - again SIGSEGV. But I found an interesting thing. When I run FP.EXE from FPC 1.0.11 (it started always O.K.), nothing done, just exit program, and then try run IDE from FPC 2.6.2 - the program starts! *Further attempts to start IDE from FPC 2.6.2 causes an exception SIGSEV.* * * *If previously run IDE from FPC 1.0.11, then IDE from FPC 2.6.2 starts.* It is really funny... Can you tell me where can I download source for IDE from FPC 2.6.2 and how to compile it? I will try it when I have a free weekend. Thank you.
