ian, thank you for your response. i didn't have any time till this weekend to do any further work hence the late reply. as it turns out this did not directly resolve my problem so in the end i put the disk back into 32Gb mode and reinstalled 4.5. using my exsting 4.3 installation i fdisk'ed ad3 and disklabel'ed ad3s3 and booted the cd and installed. then i booted into ad3s3a and disklabel,newfs,dump/restore into ad3s2a. then i tried to boot into ad3s2a and had the same problem. so i set boot0cfg to packet on ad3 and then i managed to boot up from ad3s2a! after a couple of reboots toggling packet on and off it definitely reflects the explanation in your mail. then i put the disk back into 60Gb ( without using fdisk to change the geometry ) and it still booted both ad3s1a and ad3s2a - this doesn't help me understand what was happening before but at least now i know it will work. maybe i shouldn't have set the geometry with fdisk to start with - even though i was only using the info given by dmesg? does this actually write anything to the disk anyway? thanx again, siegfried. -----Original Message----- From: Ian Dowse [mailto:iedowse@maths.tcd.ie] Sent: Monday, 24 June 2002 11:44 To: Pietralla, Siegfried P Cc: freebsd-questions@FreeBSD.ORG Subject: Re: yet another boot problem In message <16649A8D5C73D51183B80008C728EEB7CC0AAD@AUSYM103>, "Pietralla, Siegf ried P" writes: >i'm having a problem getting my new install of 4.5 to boot. i've >successfully run through the install onto ad3s3 and the boot manager for the >second disk comes up ( and lets me go back to disk one so i know it's >working ) but when i pick 'f3' it just beeps at me. i can boot into 4.3 in A beep when you press an F-key usually means that boot0 is unable to read the boot sector for the partition you selected, either because the geometry settings in the fdisk partition table don't match the BIOS, or because the cylinder number is greater than 1023. Try telling boot0 to use packet mode by running: boot0cfg -v -o packet /dev/ad3 This will cause boot0 to ignore the geometry and use LBA addressing instead.
