Hello everyone. Natty Alpha3 boots normally on the box in question, so I guess the problem was caused by some unidentified minor flaw in the build process for alphas 1&2, silently corrected by the new automated build process for alpha-20110228 and alpha3.
Aftermath: - the CD with all the four alphas (1, 2, 3 and 20110228) are perfectly readable on both my "main" machine (the one where the discs were burned) and "test" box. "dd if=/dev/cdrom.....|md5sum" results are as expected *on both systems*. - the main machine boots normally from all the four CDs - the test box rejects alphas 1&2 (BIOS does not recognize them as bootable) but boots normally from the other two alphas. Thank you all for help. Sincerely, Mikhail Maksimov On Fri, Mar 4, 2011 at 9:08 PM, Mikhail Maksimov <[email protected]> wrote: > Hi, all. > > I've got a Pentium-IV box to test Lubuntu on.
