Hello all: OK, now that I've at least identified the FDISK problem, and solved the DIR divide by zero problem, I need to work on why FreeDOS doesn't boot and/or run stably on many computers.
Fortunately, I have the Haunted HP Pavilion. I have a repeateable problem with the VOL command built into FreeCOM. Development kernel, development command.com, development sys.com. HIMEM.EXE and EMM386.EXE from emmx204.zip. Booting from USB floppy. (EDIT from Beta9SR1 CD :-)). config.sys: device=a:\himem.exe REM device=a:\emm38.exe x=test max=256M memcheck vds Boot HP Pavilion: [...] C: HD1, Pri[ 1], CHS= 0-1-1, start= 0 MB, size= 16MB WARNING: partition Pri:4 FS 06 has CHS=3584-0-1, not 1023-254-63 WARNING: partition Pri:4 FS 06 has CHS=3646-254-63, not 1023-354-63 WARNING: partition Pri:4 FS 06 is not LBA Please run FDISK to correct this - using LBA to access partition. start 3584-0-1, end 3646-254-63 D: HD1, Pri[ 4], CHS=3584-0-1, start=28113 MB, size= 494 MB FreeDOS HIMEM64 4.11 [...] HIMEM - BIOS A20 method used A:\> vol c: Volume in drive C has no label Volume Serial Number is 2640-14E4 A:\> vol d: Volume in drive D has no label Volume Serial Number is 6D08-68B3 A:\> Change config.sys to: device=a:\himem.sys device=a:\emm386.exe x=test max=256M memcheck vds and reboot. [...] EMM386 2.04 [...] selected page frame e000 not available, searching automatically using PAGEFRAME e000:0000 A:\> vol d: That's it...no output and no return. Repeat, removing MEMCHECK option from emm386. Still hangs. Remove x=test and add NOEMS. (config.sys now: device=a:\himem.exe device=a:\emm386.exe noems max=256M vds) Screen full of rapidly repeating garbage I can't read...looks like a register dump...the pattern looks like two lines but it scrolls by so fast I can't read it until I turn the power off. Add memcheck to device=a:\emm386 line. No change, rapidly scrolling garbage. Remove NOEMS. EMM386 2.04 [...] No other lines from EMM386. Boots normally, A:\> vol d: hangs. Help! How do I start to debug this?!?! This is the same machine which has FDISK overwriting the partition table whenever it is run with EMM386. Thanks.
