win32 Posted April 26, 2019 Share Posted April 26, 2019 (edited) I've been trying to install Windows 2000 in AHCI mode on an HP Z600 Workstation (5520 chipset + ICH10R) from USB. Setup only shows the USB flash drive and not the actual HDD. 48-bit LBA is enabled and I've tried numerous AHCI drivers: BWC's 7.6 drivers, then integrated extended core v16 to try BWC 8.9 drivers and even some later ones that work on 2003 x86 (9.6). The same thing keeps happening! I'd be ecstatic if I could get this to work. I'm weary of a performance hit in IDE mode, though when I tried that it still worked great, but I could still be missing out on good performance in AHCI.

Not what you asked, but you may try (if you can make an image/backup/etc,) to change the mode post-setup. For XP it is/was possible so the same should be possible on 2000. JFYI: https://msfn.org/board/topic/120444-how-to-install-windows-from-usb-winsetupfromusb-with-gui/?page=40&tab=comments#comment-884409 http://reboot.pro/topic/11729-how-to-load-sata-drivers-to-offline-windows-xp-system/ It is possible that for *some* reasons the "right" driver cannot be integrated/started/whatever in the setup. You could also try (if you want to rinstall) with a (fake/virtual) F6 floppy (via grub4dos), again tested on XP but should work on 2K as well: https://msfn.org/board/topic/154071-f6-without-a-floppy-drive/ jaclaz Link to comment Share on other sites More sharing options...
win32 Posted April 27, 2019 Author Share Posted April 27, 2019 Unfortunately, that method nor installing uniATA did anything, which means I'm stuck in IDE mode. In reality, performance doesn't seem to be too bad. USB-HDD transfers are still faster than 2003 on AHCI. Thank you for your assistance. Link to comment Share on other sites More sharing options...

Yes, a good IDE is not that much slower than a SATA with "normal" HDD's, of course SSD is another matter. The USB fastish transfer could be probably for another reason, seemingly USB transfer for FAT 16/32 was dumbed down after 2000 (NTFS should be however faster than 2K) JFYI: https://msfn.org/board/topic/125116-fat16-vs-fat32-vs-ntfs-speed-on-usb-stick/ jaclaz Edited April 28, 2019 by jaclaz Link to comment Share on other sites More sharing options...
win32 Posted June 22, 2019 Author Share Posted June 22, 2019 (edited) I found a solution: use the vanilla ntdetect.com (as opposed to the one needed for Dell machines to boot NT 5.x setup off USB). Then the 7.6 drivers work fine! I'm going back to Windows 2000 where the speed of FAT32 USB transfers will be bearable again!
