Thanks for the help. As Jeffery said, this write up on the Gentoo site seems to differ from what you're saying, unless I'm misunderstanding you. It would seem according to the Gentoo install doc that the CD is not counted. I think my confusion, or possibly worry, right now is that I did 2 hours of installation, which ends with installing grub but somehow wiping out the Gentoo installation. Can that happen? I did create the boot floppies, so maybe they will help me work out what's going on. My recollection was that last night, at the grub step where I thought I should type 'root (hd4,0)', grub complained so I tried 'root (hd0,0)' and it worked. Is there any way that grub could have thought it was installing to my CDRW drive? I doubt it, but just trying to clarify. There was still the Gentoo CD in the drive at that point, so grub would see a filesystem I suppose. Anyway, I'm sure I'll get this worked out this evening when I get back to it.

I'm making progress, but it's still not booting. Results are the same whether working from the hard drive version of grub, or a floppy made when I did the install. I reboot, come up into grub and then edit the configuration. The best I have so far is: root (hd0,0) kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r8 root=/dev/hde3 and then I type 'boot'. The machine gets further, down to the point of looking at the UDMA100 controller. It says ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA and hangs. Alt-CTL-Del doesn't work and I have to push the reset button. I assume these are just statements about how it would use the controllers if drives were there. The only drive that should exist at this point should be hda, the CDRW. I also tried root (hd0,0) kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r8 root=/dev/hde3 initrd (hd0,0)/initrd-2.4.20-gentoo-r8 It made no difference. I also tried kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r8 root=/dev/hde3 nodma and still fail, all the same way. Last evening, before I started the Gentoo install, I quickly tried to throw a copy of DOS on just to see what would happen. DOS would not boot and hung looking for CDROMS. If I booted a version of DOS that did not look for CDROMS, then DOS was fine. I'd wonder if this is an NForce2 chipset issue, but I know others have made the motherboard work, although I'm not sure if they've done it with SATA. Thanks again for all your comments.

Grub is working right, you got something else going.. It looks to me like its past grub and booting linux. Linux is trying to find your ide controller cards and locking.. Or something to that affect. That's my thought too, but slightly different. hda-hdd are the chipset EIDE controllers. It found them, and said it was going to use DMA. I don't know if this is good or bad, but that's how I read this. However, I don't know the next step: 1) Look at the drives attached to the EIDE controllers, or 2) Look for the next controller, which is the SATA controller I'm sort of guessing that it's the second option, and that possibly the initrd has a driver for the SATA controller. However, in my mind this afternoon, that seems like a leap to assume that genkernel figured out this machine had an SATA controller and then built the driver into the kernel, or included it into the initrd file so that the machine would boot. Comments? Wait.. you have kernel (hd0,0)/boot/kernel-2.4.20-gentoo-r8 root=/dev/hde3 initrd (hd0,0)/initrd-2.4.20-gentoo-r8 why don't you have /boot in front of initrd like you do the kernel?? there is no nee Did you mean to finish this thought?

I'll possibly need to ask some questions about how to do that at this point. I don't want to do a complete reinstallation just to do that, and I doubt I have to. Can I not just mount the installation CD and then somehow mount and build the kernel from what's already on my drive? I've managed to reboot from the installation CD.The boot sequence that I see when booting from the CD: NFORCE2: IDE controller at PCI slot 00:09.0 NFORCE2: chipset revision 162 NFORCE2: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA SiL3112 Serial-ATA: IDE controller at PCI slot 01:0b.0 SiL3112 Serial-ATA: chipset revision 2 SiL3112 Serial-ATA: not 100% native mode: will probe irqs later ide2: MMIO-DMA , BIOS settings: hde:pio, hdf:pio ide3: MMIO-DMA , BIOS settings: hdg:pio, hdh:pio At this point the machine happily goes on, finds all the drives on all the controllers and boots, but in my case the Serial-ATA stuff never shows up and the machine's hung. I should (hopefully) know later this evening if genkernel is the culprit. As a starting point, if I can find the config file for the kernel on my Athlon-XP CD then I'll probably get a working box. Now, what do I need to know about building a kernel by hand in the middle of the reboot and remount stuff I'm going through? Cheers, Mark -- [EMAIL PROTECTED] mailing list
