NAME
       isaset - set ISA registers

SYNOPSIS
       isaset [-y] addrreg datareg address value [mask] #for I2C-like access
       isaset [-y] -f address value [mask] #for flat address space

DESCRIPTION
       isaset  is  a small helper program to set registers visible through the
       ISA bus.

OPTIONS
       -f     Enable flat address space mode.

       -y     Disable interactive mode. By default, isaset  will  wait	for  a
	      confirmation from the user before messing with the ISA bus. When
	      this flag is used, it will perform the operation directly.  This
	      is mainly meant to be used in scripts.

OPTIONS (I2C-like access mode)
       Four  options  must  be	provided  to  isaset. addrreg contains the ISA
       address of the address register for the chip to probe; datareg contains
       the  address  of the data register. Both addresses are integers between
       0x0000 and 0x3FFF. Usually, if the chip's base address is  0x0nn0,  the
       address	register  is at 0x0nn5 and the data register is at 0x0nn6. The
       most common base address for hardware monitoring chips is 0x0290.   For
       Super-I/O chips, address register is typically at 0x2E with data regis‐
       ter at 0x2F.  The address and value parameters are two integers between
       0x00  and  0xFF.	 isaset will write value value to address address.  An
       optional mask can be provided as a fifth parameter, preserving unmasked
       bits at the written location.

OPTIONS (flat address space mode)
       In flat mode, two parameters must be provided. address contains the ISA
       address of the register to write to; it is an  integer  between	0x0000
       and 0xFFFF. Basically, it is the sum of the chip's base address and the
       chip register's address. isaset will write value value at this address.
       An  optional  mask  can	be  provided  as a third parameter, preserving
       unmasked bits at the written location.

WARNING
       Poking around in ISA data space is extremely dangerous.	Running isaset
       with  random parameters can cause system crashes, data loss, and worse!
       Be extremely careful when using this program.
