28.12.2012 DELL 1645 - FLASH BIOS FROM LINUX
How to flash the BIOS on DELL Studio XPS 16 (Model 1645)
- Download the windows flash utility from DELL support
- Run the exe file under wine
- This will unzip
1645_A13.exe in your chosen folder
- Run
1645_A13.exe
- You will now get an error message, don't click OK!
cd ~/wine/drive_c/users/[username]/Temp/WinPlash- Copy the
.WPH file to a safe folder, this is the BIOS data.
- Download the PHLASH16.EXE utility
- Download the Freedos
- Setup a boot-disk
qemu-img create freedos.img 16Mqemu-kvm -hda freedos.img -cdrom fdbasecd.iso -boot d- I disabled all optional install options, don't know if this is necessary,
You will probably have to make sure the drive is formated with FAT16
- Copy the BIOS and flash utility to the boot-disk
losetup -f freedos.img
kpartx -a /dev/loop0
mkdir tmp
mount /dev/mapper/loop0p1 tmp
cd tmp
cp ../BIOS1.WPH .
cp ../PHLASH16.exe .
cd ..
umount tmp
rmdir tmp
- Get some important info about the partition-table
fdisk -l freedos.img

The count=63-part is from 63 sectors/track
dd if=/dev/mapper/loop0p1 of=freedos_part1.imgcat {freedos_mbr.img,freedos_part1.img} | gzip -9 > freedos_combined.img.gz- Install memdisk
zypper in syslinux
cp /usr/share/syslinux/memdisk /boot
- Add a new entry in the bootloader
- This is for grub:
###Don't change this comment - YaST2 identifier: Original name: linux###
title BiosUpgrade
root (hd0,1)
kernel /boot/memdisk harddisk c=32 h=16 s=63
initrd /boot/freedos-minimal-combined.img.gz
For grub2, you'll need something like this:
For some reason I could not get this to work with the gzipped image.
menuentry 'BiosUpgrade' {
insmod part_msdos
insmod ext2
set root='hd0,msdos4'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos4 --hint-efi=hd0,msdos4 --hint-baremetal=ahci0,msdos4 772f3686-9f80-4c06-b47f-28a6424be960
else
search --no-floppy --fs-uuid --set=root 772f3686-9f80-4c06-b47f-28a6424be960
fi
echo 'Loading FreeDos'
linux16 /boot/memdisk harddisk h=16 s=63 c=32
echo 'Loading init disk'
initrd16 /boot/freedos_combined.img
}
It shoud probably be placed somewhere in /etc/grub.d/40_custom
- Disconnect the loop drive:
kpartx -d /dev/loop0
losetup -d /dev/loop0
- Reboot and pray!
Vi bedriver endelig lyssetting.
