Hi Shane, summary of your mails... C000: Video ROM. At C900 are strings S3 Corp. and Trio64. CC00: PXE ROM by Argon Technologies CD00 to EFFF apparently FF JEMM386 with NOEMS X=CC00-CFFF NOINVLPG DOS uses d008 to db99, xcdrom doslfn etc high nothing in MEM /E, largest exe 623k, low 639k Note that if accessing dc00 to efff would trigger problems, you would not notice as this area is not filled by you here... NOEMS but no X option: DOS uses cd08 to d899, similar comment to previous, you do not fill d900 to efff so that area might or might not be problematic. JEMM386 seems to assume that the PXE ROM ends at ccff, matching your ff from cd00. X option but no NOEMS: largest exe 567k, EMS with page frame at d000 DOS does not seem to use any UMB at all, did you forget DOS=HIGH,UMB here? No X option and no NOEMS: DOS just crashes, exception 0D at c800:11e5 etc ss:esp at d0de:4, ebp=a0 ebx=7ff0007 edx=d1 esi=40fa0, edi=90fa0, ds=70, es=b800, fs=d1, gs=f000, code: 9c 2e ff 1f... which is pushf or pushfd followed by call far [cs:bx] or [cs:edi] It is interesting that c800 is mentioned here, leads to the question whether VGA ROM is only c000-c7ff and some extra ROM is at c800-cbff? The crash is a stack overflow with stack at a location in d000 area but then your other examples do use the d000 area for UMBs, odd. The f000 ROM and b800 screen segments might mean that something in ROM tried to display a message when the stack overflow happened. Then the original crash would have been at some other place, not logged by jemm386...? You could try to loadhigh / devicehigh some more things to fill more of the UMB area to get more insights about which areas are bad.

Re: [Freedos-user] FreeDOS on Virtual PC 2007
Are the BLASTER settings described anywhere in detail? VPC says it emulates the Creative Labs Sound Blaster 16 ISA Plug and Play. Maybe my settings are wrong. You can use the GETSB.EXE tool which is contained in HXGUI (http://www.japheth.de/hx.html). It reads the SB16 mixer status directly, thus it's able to tell the true values for IRQ and DMA. A PnP card usually has to be enabled - for SB16, there was a tool DIAGNOSE.EXE, which did this. But IIRC this isn't needed for VPC, the SB16 card is enabled automatically. -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.

Hi! Line #1 in batchfile 'A:\INSTALL.BAT' too long Please post the first line of A:\INSTALL.BAT. Good catch! 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. Very strange. Maybe you saved it in Unicode / UTF-8? Or in Word or something ;-) You could try other free or shareware editors like TextPad to make sure that your file is really text. Of course it could also be the case that something on your filesystem confuses DOS and the gibberish is not even part of what your Notepad put in the file. Try using chkdsk / scandisk. anyone recommend software to create floppy images without needing an actual floppy drive? In Linux: just mount the image or use mtools.

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?
