Linux doesn't need the Intel Application Accelerator -- and only /older/ versions of Windows would. Again, the problem here is that in order to boot at all, the BIOS has to be able to see the drive in order to start the boot process. Linux doesn't use the BIOS, so once the system gets as far as booting the Linux kernel, everything is fine. > > One thing to note in the page above however is that the Intel i830M > > chipset is listed, which is what is used by the Thinkpad T23.

You might be right, it's just difficult to verify that to be sure. If I was buying a hard disk, what I'd want is some kind of spec for the T23 to know that the disk would work and wouldn't have a problem -- but unfortunately I can't find something that says what the maximum hard disk size the T23 can accept. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Jan 5 - Building a Community Site with Drupal Feb 2 - Zimbra Mar 2 - MHVLUG 8th Anniversary - Show and Tell
