Can I do something for debugging? I've got the same problem. I installed a -current snapshot about 2 1/2 weeks back, and the fdisk editor obviously wrote the partition tables with a different assumption about disk geometry than 4.7-stable. Now, my partition tables have boundaries that Linux's fdisk disagrees with. For example, using Linux fdisk from my Gentoo install: fdisk -l /dev/hda Disk /dev/hda: 255 heads, 63 sectors, 2432 cylinders Units = cylinders of 16065 * 512 bytes Device BootStart EndBlocks Id System /dev/hda1 136289138+ a0 IBM Thinkpad hibernation Partition 1 does not end on cylinder boundary: phys=(573, 11, 63) should be (573, 254, 63) /dev/hda2 *37 765 5855692+ c Win95 FAT32 (LBA) Partition 2 does not end on cylinder boundary: phys=(1023, 2, 63) should be (1023, 254, 63) /dev/hda3 766 1403 51247355 Extended /dev/hda4 1404 2432 8265442+ 82 Linux swap /dev/hda5 766 767 16033+ 83 Linux /dev/hda6 768 778 88326 83 Linux /dev/hda7 779 798160618+ 83 Linux /dev/hda8 799 831265041 83 Linux /dev/hda9 832 1403 4594558+ 83 Linux I never had this problem with FreeBSD-stable and Linux. And now, with the DP2 install CD, I can't delete any partitions with D, as the cursor just moves up. Here is FreeBSD's idea of my disk geometry: C/H/S == 38760/16/53 Here is what Linux reports: dmesg | grep hda ide0: BM-DMA at 0x1080-0x1087, BIOS settings: hda:DMA, hdb:pio hda: TOSHIBA MK2016GAP, ATA DISK drive hda: 39070080 sectors (20004 MB), CHS=2432/255/63, UDMA(33) So, I tried pressing G, and entering in 2432/255/63, but the DP2 fdisk editor still wouldn't let me delete any partitions. I suppose GEOM is the culprit here. To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-current in the body of the message

I think this patch solves the problem.

fdisk editor in DP2
I'm trying to install DP2 to old machine (P2 dual). This box has 2GB IDE disk and ran NT4 before. When entering fdisk editor after booting from CD-ROM, I cannot delete NTFS partition by D key. D key only shows cursor up (NTFS is at offset 63, offset 0 seems boot selector for NT). Can I do something for debugging? -- Jun Kuriyama [EMAIL PROTECTED] // IMG SRC, Inc.

Re: fdisk editor in DP2
Is the disk geometry displayed correctly? I had a similar problem with DP2 on a Maxtor Atlas 10k III (18.4GB). Geom displayed in fdisk w/zero cylinders. Manually setting the geometry fixed the problem. On Tue, 19 Nov 2002, Jun Kuriyama wrote: I'm trying to install DP2 to old machine (P2 dual). This box has 2GB IDE disk and ran NT4 before.
