ATmega168 Programming: Which board to use?

i've been following along book "make: avr programming: learning write software hardware" , book says "select tools -> board -> arduino pro mini (8 mhz) w/ atmega168" using atmega168pa-pu, , running no external clock. however, there no "arduino pro mini (8 mhz) w/ atmega168" in board section. closest thing "arduino pro or pro mini (3.3v, 8mhz) w/ atmega168" if select , try flash chip, error:

code: [select]

avrdude: device signature = 0x1e940b
avrdude: expected signature atmega168 1e 94 06
        double check chip, or use -f override check.

i'm kinda new @ this, suggestions appreciated!

thanks!

by "flash chip" mean "burn bootloader" or  "upload using programmer"?  those talk hardware directly.   might able work around problem changing:

code: [select]

pro.build.mcu=atmega168
to

code: [select]

pro.build.mcu=atmega168pa
in boards.txt.

if trying upload using normal usb cable should not getting error since arduino bootloader should  return atmega168 signature when running on atmega168pa.
