Hi Phillipe,

Not to be the bearer of bad news, but yeah - the Phoenix BIOS is likely a contributing factor.   We use a common boot 
platform from CFs on a wide variety of x86 boards, both embedded and not.  Consistently machines with Award or AMI 
BIOSes takes a fraction of a second to load the 1.5MB .boot image - the little dots just zip across the screen; however,
 the Phoenix based boards take a very long time (10+ seconds).  We've tried both ipl-pc2 and ipl-pc2-flop, as well as 
some 3rd party ipls without any change in measured speed.

You could try talking to your board manufacturer - maybe they can do something to help?  For our systems boot time isn't
 critical, so while it was a nuisance we never followed up on it.
