====== 50 CentOS5.7 ドライバ組み込み ======

CentOS 5.7 のインストールCDにBCM57810 10 Gigabit Ethernetのドライバを組み込んだ時のメモ

===== CDの内容をコピーする =====

<code console>
# mkdir /mnt/work/old_cdrom
# mkdir /tmp/work/new_cdrom
# mount t iso9660 -o loop CentOS-5.7-x86_64-netinstall.iso /mnt/work/old_cdrom
# rsync -av /mnt/work/old_cdrom/ /tmp/work/new_cdrom/
# umount /mnt/work/old_cdrom/
</code>

===== initrb.imgを展開 =====
<code console>
# cp /tmp/work/new_cdrom/isolinux/
# mkdir initrd_work
# cd initrd_work
# gunzip -c ../initrd.img |cpio -i
# ll /tmp/work/new_cdrom/isolinux/initrd_work

===== rpmからドライバを取り出す =====
<code console>
# mkdir /tmp/work_driver
# cd /tmp/work_driver
# rpm2cpio ../kmod-hp-netxtreme2-7.4.25-2.x86_64.rpm |cpio -i

===== ドライバモジュールをフォルダに入れて、再度固める =====
<code console>
# cd /tmp/work/new_cdrom/isolinux/initrd_work/modules
# mkdir unpacked
# cd unpacked
# gunzip -c ../modules.cgz |cpio -id
# cp /tmp/work_driver/lib/modules/2.6.18-274.el5/extra/hp-netxtreme2/bnx2x.ko /tmp/work/new_cdrom/isolinux/initrd_work/modules/2.6.18-274.el5/x86_64/bnx2x.ko
# find 2.6.18-274.el5 | cpio -ov -H crc | gzip > ../modules.cgz
# cd .. && rm -rf unpacked
</code>

===== modules.aliasを修正 =====
<code console>
# modinfo /tmp/work/new_cdrom/isolinux/initrd_work/modules/2.6.18-274.el5/x86_64/bnx2x.ko

===== modules.depa入って無ければ、下記追加 =====

  bnx2x: 8021q mdio

===== initrd.imgをまた固める =====

<code console>
# cd /tmp/work/new_cdrom/isolinux/initrd_work
# (find . | cpio --quiet -c -o) > ../initrd.img
# cd .. && rm -rf initrd_work
# gzip initrd.img && mv initrd.img.gz initrd.img
</code>

===== isoイメージにする。 =====
<code console>
# cd /tmp/work/new_cdrom/
# mkisofs -o ../CentOS-5.7-x86_64_NEW.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -T .
