2. Install dmidecode ports on FreeBSD 9.0 RC1
Path : /usr/local/sbin/dmidecode
- # cd /usr/ports/sysutils/dmicode/
- # make install clean
- # ./usr/loacl/sbin/dmidecode | grep Name
- Product Name : VirtualBox
3. Modify /usr/src/sys/amd64/amd64/machdep.c to add the string as follows
- strncmp(sysenv, "VirtualBox", 10) == 0 ||
4. Compile your kernel
- # cd /sys/amd64/conf
- # cp GENERIC NASBSD9
- # ee NASBSD9
- or put the file of NASBSD9 to /home/backup, and set soft link
- #cd /usr/src/sys/amd64/conf
- #ln -s /home/backup/NASBSD9
- To compile your kernel
- # cd /sys/amd64/conf
- # config NASBSD9
- # cd ../compile/NASBSD9
- # make depend
- # make
- # make install
- # reboot
- # uname -a
5. Installing GRUB2
- Create an EFI system partition
- On Ubuntu 11.10
- $ apt-get install gdisk ufsutils
- $ gdisk /dev/sdx
- EF00
- using 'gdisk' to partition an GPT format disk with an EFI system partition.
- $ mkfs.vfat -F32 /dev/sdx1
- On FreeBSD 8/9
- # gpart create -s GPT /dev/adax
// ref to solve efi booting
// need to add product name from smibios, ex:VirtualBox
http://forums.freebsd.org/showthread.php?t=12198
//must to format FAT32 on flash disk in order to access EFI system for montherboard boot up.
mkfs.vfat -F32 /dev/sdc1
gpart create GPT /dev/ada0
build grub1.99 rc1
./configure LEX=/usr/local/bin/flex --with-platform=efi --target=x86_64
- LEX=/usr/local/bin/flex
- I installed the latest port (flex-2.5.35_4) from /usr/ports/textproc/flex
- cd /usr/ports/lang/gcc44
- make install

// 宣告一塊虛擬memory disk -> md0
#mdconfig -a -t vnode -f _.disk.image
// 將_.disk.image 掛載在/mnt
#mount /dev/md0a /mnt
// 卸載 md0
#mdconfig -d -u 0
---------------------------------------------------
// Make a cpio+gz image
$find . | cpio -ocvB | gzip > /usr/src/tools/tools/nanobsd/nanobsd.cpio.gz
解壓縮
$gzip -dc folder1.cpio.gz | cpio -idv

# mkdir /tmp/ramdisk; chmod 777 /tmp/ramdisk
# mount -t tmpfs -o size=256M tmpfs /tmp/ramdisk/
