Hello everybody!
I have a Ga-ep45-ud3r mobo with ich10r host and Bios version F4. If Sata disk access is set in Bios to P-Ata compatibility mode, then W2k-Xp bootup is slow (35s) for still unclear reasons. And if Sata disk access is set in Bios to Ahci, then OS bootup gets very fast (OS disk is an X25-E, W2k boots in 15s and Xp in 9s, including nVidia video driver).
But then, in Ahci mode, the Bios gets very slow. The video card displays its data for a few seconds, and then the Bios takes 17s before giving control the the OS boot sequence, which is far too long.
From what's displayed, it seems that Gigabyte's Bios calls a routine supplied by Microsoft, as soon as the ich10r is set to Ahci or Raid, and this routine takes about 15s. Right?
By the way, this mobo has also a JMicron 363 P-Ata+Sata host on board, which also slowed down the Bios pretty much the same way when in Ahci mode, before I shut off the JMicron.
So:
- Can I improve this time through some settings?
- Does your mobo's Bios run faster than 17s in Ahci mode? What's your model then?
- Does an Intel mobo, with an Intel Bios, run faster than 17s in Ahci mode? Observed figures?
- Or do nVidia chipsets manage it better?
Thanks!
