All: thank-you for the help so far. I have posted this on gentoo-user as well, and will continue to work with folks individually here or publically on that list.<br><br>The responses so far have helped - Bigfish (Richard), I may respond directly to your RFI as you may be able to pinpoint the driver(s) I'm missing. I have added driver support in newly compiled kernels and gotten different errors - but I think I'm close.
<br><br>Again all - thanks. I'll pursue on gentoo-user...<br><br>Gpm<br><br><div><span class="gmail_quote">On 11/3/06, <b class="gmail_sendername">Ladislav Laska</b> &lt;<a href="mailto:ladislav.laska@...">ladislav.laska@...

modules for your IDE controller are loaded in initrd (or compiled into<br>kernel).<br><br>You can do this by selecting the second choice in grub (rescue). It<br>will boot into busybox (a very basic shell) and you should be (un)able
<br>to mount filesystems. I don't know what exactly will busybox do for<br>your, but maybe you will need to create device node by hand.<br><br>For more informations, please write to gentoo-user list, or contact me<br>personally (but NOT this list, unless this is gentoo-installer's
<br>problem).<br><br>On 11/3/06, Greg Morin &lt;<a href="mailto:gpmorin@...">gpmorin@...</a>&gt; wrote:<br>&gt; Good day,<br>&gt;<br>&gt;&nbsp;&nbsp;I've installed (several times) on a ThinkPad T-40, trying both manual<br>
