    I tested your batch file. But it also only triggers a cold start. It would also have surprised me, because your DEBUG instructions correspond to mine. The following code is from Scott Mueller (URP, 2nd Ed., p. 828):
    Code:
    DEBUG
    -N WARMBOOT.COM
    -A 100
    MOV AX,0040
    MOV DS,AX
    MOV WORD PTR [0072],1234
    JMP FFFF:0
    
    -R CX
    10
    -W
    -Q
    I use WARMBOOT.COM on all my PC's and it works otherwise perfectly.

    I use this one:


    goto begin

    e 40:72 34 12
    rcs
    ffff
    rip
    0000
    g

    :begin
    debug<c:\reboot.bat


    See what that does.

    I also have a 16 byte com file (reboot.com) that does the same thing if you'd like to try that one.

    DOS: cold boot / warm boot

    One should actually think that the key combination CTRL+ALT+DEL triggers a warm start. On all my DOS computers it's so; it always was, but ... However, I have an IBM PC 5150 motherboard where this is not the case. The key combination always triggers a cold start! Also a mini program created with DEBUG, which should trigger a warm boot, creates only a cold start. Does anyone have an idea why?
