ESXi 4.1 - questions about GRUB

Can someone explan about bootloader for ESXi 4.1?

Does it use GRUB?   Does it use an MD5 encrypted password?

ESXi uses syslinux/isolinux - not Grub

syslinux then chainloads mboot.c32/safeboot.c32 which then loads the kernel

I asked this earlier but did not get a response:

  Does ESXi 4.1 boot-loader use an MD5 encrypted password?

  Thanks.

the bootorder is syslinux > mboot32 > ESXi kernel

the first two dont use passwords so I dont think the bootloader uses md5 ...

maybe I missunderstand your question ...
I see you have several questions guiding in one direction.

Do you need to proove that an ESXi cant be exploited if some has local access or something like that ?

Hm - that will be tricky if not impossible.

If you allow someone to change the boot-medium you also open the door for using ESXi from other media than the local disk.

Personally I use a ESXi LiveCD that boots a fully functional ESXi from a CD - using a USB-stick is another way to do that.
So when I need to read VMFS I can do it by several different approaches.


Only option to prevent me from reading the VMFS or manipulating the local ESXi system you must lock the BIOS
