Hi,

I wonder if I can update a phoenix bios (Tyan Tiger MPX MB) from a bootable
CD?

I made an iso image on linux, adding the bios burn utility and the rom image
to the iso image. (using mkisofs)

After burning it on CD and booting with it, FreeDOS (9.0 rc3) automatically
puts those extra files to X: ramdrive.

Now I'm hesitating do I dare to go ahead and burn the bios from the
ramdrive, or do I risk getting a coaster MB util I can get a new physical
bios chip replacement.

Any experiences with this one?

I make bootable ISO images for flashing BIOS using drdflash.exe
http://ftp.sanguine.jp/pub/sahughes/drivers/via/VIA_EPIA_Mini_ITX_Mainboard_BIOS_update/
I make a floppy with that program.add the flash program and the .rom
file.Then use the floppy on Nero to make a bootable CDR/W disk.
I'm not sure I would trust a flash to a,"RAM"drive.

I managed to update without any problems using pure linux tools, no floppy
drive at all:

Using Mandrake 9.2, but should work an any distro, the step:

Mount the FreeDOS floppy image to a directory

sudo mount -o loop fdboot.img /mnt/floppy
mkdir tmp
cd tmp
unzip ../2466_405.zip ; unzip the bios files
sudo cp * /mnt/floppy/ ; copy those to mounted floppy image
sudo umount /mnt/floppy
mkdir cd
mkisofs -b fdboot.img -o cd.iso cd

Burn the resulting iso image cd.iso to CD using k3b.

Booting the CD, select option 3, no drivers to go to A: prompt.
Run the flash utility.

Worked like a dream.
