How to rebuild/upgrade glibc



This sample is update Glibc 2.5 to 2.7 (RHEL 5.3 x86)

Download package
ftp://ftp.gnu.org/gnu/glibc/glibc-2.7.tar.gz
ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.18.tar.gz
ftp://ftp.gnu.org/gnu/glibc/glibc-linuxthreads-2.5.tar.bz2


Prepare the kernel headers
# tar zxvf linux-2.6.18.tar.gz
# cd linux-2.6.18
# make mrproper
# make menuconfig
(you don't need to actually configure anything; just accept the defaults and then exit out of menuconfig)
# make dep  (ignore warning)
# mkdir -p /usr/include/linux-2.6.18
# cp -a include/linux /usr/include/linux-2.6.18/
# cp -a include/asm* /usr/include/linux-2.6.18/


Building glibc
# tar zxvf glibc-2.7.tar.gz  
# cp glibc-linuxthreads-2.5.tar.bz2 /glibc-2.7                      
# tar jxvf /glibc-2.7/glibc-linuxthreads-2.5.tar.bz2
# mkdir /build
# cd /build

# ../glibc-2.7/configure --prefix=/usr --disable-profile --enable-add-ons \
  --with-headers=/usr/include/ --libexecdir=/usr/bin
#vi config.make
add "-march=i686" after "CFLAGS = -g -O2"
# make  (If you meet error while make, you need to execute "make clean", then make again)
# make install
# ls /lib/libc-*
libc-2.7.so

Use AMISCE tool to update BIOS configuration under linux

Use AMISCE tool to update BIOS configuration under linux

Test fucntion without change dump file
1.Copy SCELNX_64 to Linux_Flash folder
2.cd Linux_Flash
3#afulnx_64 /MAKEDRV
4.#afulnx_64 /GENDRV [Option 1] /    (ex:./afulnx_64 /GENDRV 2.6.32-71.e16.x86_64 /)
[Option 1]: Specific kernel source 'KERNEL=XXXX' , #uname-r to check
5.#make
6.#SCELNX_64 /o /s nvram.txt /h Hii.db /v /q
7.Reboot to BIOS, change some BIOS configuration
8.Save,boot to linux
9.Boot to OS, cd AMI_SCE folder
10.#SCELNX_64 /i /s nvram.txt  (Restore BIOS to original configuration)
11.Reboot to BIOS, check if configuration is back

--------------------------------------------------------
Dump all BIOS configuration:
# ./SCELNX_64 /o /s NVRAM.txt

-----------------------------------------------------
Change password by modify dump file
Set BIOS Administrator/User password through SCE utility:
0. Set BIOS Administrator/User password and dump nvram file(contain password) with below command
   ./SCELNX_64 /o /c /l list.txt /n nvram.txt /h hii.db
1. Dump nvram file(no password) with below command
   ./SCELNX_64 /o /c /l list.txt /n nvram.txt /h hii.db
2. Edit dumped nvram file to change "Variable Data" about AMITSESetup to set BIOS password. (see nvram.txt in step 0)

3. Update nvram file to system using following command.
   ./SCELNX_64 /i /l list.txt /n nvram.txt
4. Reset system and check if BIOS password is set.
