system boot taking more time, unable to mount vfat, linux partitions,

[Anugunj Anuj Singh]

Hi,
I am using FreeBSd6.2
My FreeBSD takes around 90 seconds after detecting my hard disks.
I use my second hard disk as a backup to store data, FIrst hard disk has
linux and FreeBSD installed. I can mount vfat partitions from second
hard disk but unable to mount it from FreeBSD. it shows me incorrect
super block. 

Timecounter "TSC" frequency 851937863 Hz quality 800

How to change it's settings to skip 90seconds delay at booting time?

Output of fdisk command is

[root at anugunj /etc/mail]# fdisk

parameters extracted from in-core disklabel are:
cylinders=159560 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
