Hello All.
I was wondering if anyone could told me how to make a bootsector that loads 
system files (for example: ibmio.com and ibmdos.com). And how to make 
ibmio.com and ibmdos.com. I have already made a bootsector but it only writes 
a message that this disk is not bootable, let me show it to you:
BSect           SEGMENT PARA PRIVATE 'CODE'
                ASSUME CS:BSect, DS:BSect
                ORG     0                   ; Boot sector will be here
BootSector      DB      0EBh,03Ch,090h
;                JMP      SHORT BootCode

                DB      '        '
BootBPB         DB      25 DUP (0)
                DB      00              ; Drive number hard disk (now floppy)
                DB      00              ; Reserved
                DB      29h             ; Extended boot signature
                DD      00000000        ; Volume serial number
                DB      'SILENCER   '   ; Volume label
                DB      'FAT12   '      ; File type
BootCode:       MOV     AX,7C0h         ; Standard loading place for
                MOV     DS,AX           ; boot sector
                MOV     ES,AX
                MOV     SI,OFFSET BootMsg
MsgLoop:        MOV     AL,[SI]
                CMP     AL,0
                JE      MsgDone
                MOV     AH,0Eh
                INT     10h
                INC     SI
                JMP     SHORT MsgLoop
MsgDone:        MOV     AH,0
                INT     16h
                INT     19h             ; Warm boot
BootMsg         DB      'This disk is not bootable.',13,10
                DB      0
                ORG     510
                DB      55h             ; Boot sector has to end with
                DB      0AAh            ; these bytes, in this order
BSect        ENDS

Another question. Is it possible to create your filesystem ?
