Model: M537 Rev 3.1
Operating System: Other (Note: might work with other versions of this os.)
This bios is useful because it supports hard drives up to 32 GB. This is not the newest, but it does support the large HDs.
Remember, this is for the VX Pro M537 only. If you have revision 5.2 or higher, you need to keep looking (5.2 and higher are DMA boards).
