Stacks Ü ßßßßßßß Supports the dynamic use of data stacks to handle hardware interrupts. You can use this command only in your CONFIG.SYS file. Syntax: STACKS=n,s n Specifies the number of stacks. Valid values for n are 0 and numbers n the range 8 through 64. s Specifies the size (in bytes) of each stack. Valid values for s are 0 and numbers in the range 32 through 512. Default settings The default setting for the stacks command are 0,0 for IBM PC, PC/XT, and IBM PC-Portable; and 9,128 for other systems. Special cases for stack allocation Upon receiving a hardware interrupt, FreeDOS allocates one stack from the specified number. If the values for n and s are 0, each running program must have enough stack space for hardware interrupt drivers. If your computer becomes unstable, use the defaults. Example: To allocate 8 stacks of 512 bytes each for hardware-interrupt handling, add the following line to your CONFIG.SYS file: stacks=8,512
