<DIV><FONT face=Arial size=2>Well, IMHO, that's because, normal
conventional BIOS do spend much of time in</FONT></DIV>
<DIV><FONT face=Arial size=2>de-compressing its <<modules>>. as you
can see those "modular BIOS" banner.</FONT></DIV>
<DIV><FONT face=Arial size=2>load one module, decomp it, execute it, report
module exit status and etc..</FONT></DIV>
<DIV><FONT face=Arial size=2>256kb is not so vast space for even bios written in
full .asm language.</FONT></DIV>
<DIV><FONT face=Arial size=2>and some modules require the cpu to be in real
'real mode' some others run in something like</FONT></DIV>
<DIV><FONT face=Arial size=2>flat mode. so there should be some resets
also.</FONT></DIV>
<DIV><FONT face=Arial size=2>hope it helps.</FONT></DIV>
