hp 6735b / windows cd boot issue: stop 7b
Issue I ran into yesterday relating to our new set of HP 6735b laptops (and likely other new SATA equipment)...
Basically, I was attempting to reformat the systems with our XP Pro CD, and the systems would BSOD with a 7b error code. Tried multiple systems, multiple CD's, same issue.
Called HP - these laptops are shipping with a BIOS setting that is not compatible with XP install CD's (as I understood the rep).
To check / change:
Boot, F10 (bios)
Select System Config > Device Config > Sata Device Mode
Our laptops are set to AHCI; in order to boot off an XP cd, had to change to IDE.
For what it's worth, I can still use the image I had already configured, even though when changing these settings the BIOS warns you may need to reinstall your OS.
Apparently AHCI is used with Vista, per wikipedia [ame]http://en.wikipedia.org/wiki/Advanced_Host_Controller_Interface:[/ame]
Hope it helps! I'll post back in once I find out if I can image an IDE-set laptop to an AHCI-set laptop.
AHCI is fully supported out of the box for Microsoft Windows Vista and the Linux operating system from kernel 2.6.19. NetBSD also supports drivers in AHCI mode out of the box in certain versions. OpenBSD has had an ahci driver since OpenBSD 4.1. FreeBSD supports AHCI as well. AHCI support for Solaris 10 has been introduced in the 8/07 release . Older operating systems require hardware-specific drivers to support AHCI.
My apologies if I'm wrong on any of the AHCI info - it's all new to me! :p I did try to slipstream some AHCI drivers onto my XP install CD, but didn't have any luck.
