 .SH OPTIONS
 .TP

+.B \-f
 Enable flat address space mode.
 .TP
-.B -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.

 .SH OPTIONS (I2C-like access mode)
-Four options must be provided to isaset. \fIaddrreg\fR contains the
-ISA address of the address register for the chip to probe; \fIdatareg\fR
-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.

+The most common base address for hardware monitoring chips is 0x0290.
 For Super-I/O chips, address register is typically at 0x2E with data
 register at 0x2F.
-The \fIaddress\fR and \fIvalue\fR parameters are two integers between
-0x00 and 0xFF. isaset will write value \fIvalue\fR to address \fIaddress\fR.
-An optional \fImask\fR can be provided as a fifth parameter, preserving
-unmasked bits at the written location.

 .SH OPTIONS (flat address space mode)
 In flat mode, two parameters must
-be provided. \fIaddress\fR 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 \fIvalue\fR at this address.
-An optional \fImask\fR can be provided as a third parameter, preserving
-unmasked bits at the written location.

 .SH 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.
