1. Enable SSH on your ESXi
2. Connect with Putty
3. Paste the following commands into your Putty:

cp /tardisks/s.v00 /vmfs/volumes/datastore1/s.vtar
cd /vmfs/volumes/datastore1/
vmtar -x s.vtar -o output.tar
rm s.vtar
mkdir tmp
mv output.tar tmp/output.tar
cd tmp
tar xf output.tar
rm output.tar

4. connect with Filezilla or WinSCP to your ESXi
5. copy "/vmfs/volumes/datastore1/tmp/bin/vmx" to Windows-Machine
6. inject new BIOS440.rom into vmx with EsxBiosTools v3.0.0
7. upload modded vmx to ESXi (same path where you downloaded it!)
8. paste following commands into Putty:

chown 201:201 /vmfs/volumes/datastore1/tmp/bin/vmx
chmod 4755 /vmfs/volumes/datastore1/tmp/bin/vmx

tar -cf /vmfs/volumes/datastore1/s.tar *
cd ..
vmtar -c s.tar -o s.vtar
xz -z s.vtar
gzip s.vtar.xz
mv s.vtar.xz.gz s.v00

9. copy your new s.v00 to bootbank:

cp /vmfs/volumes/datastore1/s.v00 /bootbank/s.v00

REBOOT ESXi

DONE!

这个方法适合于6.5及以下版本
