I presume you have seen the hint at http://www.centos.org/modules/newbb/viewtopic.php?topic_id=2126&forum=27

regarding ACPI. That guy found satisfaction by disabling it in BIOS. I see that you have tried ACPI fixes, but it may be worth a careful retry after re-determining the proper command-line option. Is it just something like
  linux acpi=off
at the install command prompt. There is a HOWTO at:
  http://www.columbia.edu/~ariel/acpi/acpi_howto.html

I have installed centos4.2 (on other MBs) without difficulty, but I do recall several other threads re other OS installs on other MBs reporting ACPI problems during install (but not after install) -- I guess the install kernel doesn't always provide compatibility with all hw environments.

Hmmm, now that I think of it, I recall centos installs having sporadic difficulty with different CDROM devices. In particular, the ISO image verification step often failed, but the install proceded ok, if verification was skipped. Do you have other CDROMs you can try?

Another thought: have you tried text-mode install?

Quoting Michael J McCafferty <[EMAIL PROTECTED]>:

All,
I am having a hardware issue... or maybe it's a software issue. Whatever it is is driving me nuts. It takes an hour to install a minimal install of CentOS
4.2 (tried 4.1 too), either the ServerCD or from the regular set of CD's.
See it psyched me out, I thought it was hanging at /sbin/loader, but it was just going VERY slow... it takes about 10 to 15min to get past that point. Once it gets past that point, the installation program runs super slow. It's
almost exactly as this person describes here:
http://www.experts-exchange.com/Operating_Systems/Linux/Linux_Setup/Q_21378016.html

  But none of the proposed fixes solve my problem.

To top it all off, once the system is installed, it's glacially slow to boot
up.

Hardware:
ASUS P4P800-MX-UAYZ Motherboard
1 80GB Western Digital SATA HDD
No floppy
No IDE CDROM
Celeron 2.8Ghz
1GB Kingston PC2700 RAM


CentOS 3.5, OpenBSD and Debian Sarge all install fine, at regular speed. I have 6 of these boards, all exhibit the same behavior. WTF ? It's not an option to
not support CentOS 4.

I have tried several different ISO images, from different mirrors, on different media, burned on different burners. I have tried USB CDROM (preferred method), and IDE CDROM. I tried different boards (same model of course), with different
CPU's (2.53 and 2.8), and different RAM.

I have tried disabling Audio, Floppy, USB, ACPI. I have tried the SATA in
"Compatible" mode and "Enhanced" mode.

Thoughts on boot flags, other BIOS settings ? I need to be able to customize each installation, but I can't have it take so freakin' long ! Yep, I Googled
it, but maybe your suggestions will be better than those I found.

Thanks In Advance,
Mike
