Judging on a FREQ value (about 125) from the boot logs, the BIOS had set up PLL to 50 MHz (125/192 ~ 32/50) which should have "spoilt" the value in the f_CNT register. Hence, we may guess that the BIOS had saved the f_CNT value beforehand. If not, there's not much we can do except to guess at the DPLL frequence that BIOS might have set. MBR, Sergei
