>Description:
I installed 6.0 beta on a rather generic i386 machine:

p4m800pro-m v2.0 by ECS

http://www.ecsusa.com/ECSWebSite/Product/Product_Detail.aspx?DetailID=673&CategoryID=1&DetailName=Feature&MenuID=16&LanID=9

and the install went OK, but it would not successfully boot from hard disk, halting after:

NetBSD MBR boot
NetBSD/x86 ffsv2 Primary Bootstrap
[silence]

The install complained once that the disk geometry could not be uniquely matched:
Bios: 1024/16/63
Prob: 1023/255/63

I tried both the auto and manually entering the c/h/s.

I used the entire disk so no added confusion there.  The dmesg is at the bottom, after other comments.

It did install and boot correctly on this machine with version 5.1, although on one install strange things happened such as creating the main partition past the end of the disk.

How can I help debug this?  It has an AMI bios version 2.59 (latest from manufacturer), Maxtor 40gb hard disk, etc.

----------

On a side note, I did install the beta on my dell poweredge 1850, and it seemed to work, although the long standing problem with the power control has not improved.  Still needs to boot w/o the ACPI. (-1 or -2 on the command line).

----------

I also tried installing 6.0 beta on sun ultra 10 (sparc64) and it seemed to work including 4k disk sectors:

 If it got as far as showing the ffs2 message then the chs values won't matter.

 I had an issue booting via grub where the console was getting set to
 com0 instead pc by default.

 Try booting from the install cd, and exit to shell (^C will do).
 Then run 'installboot -e -v wd0' to look at the options, and maybe
 force the console with '-o console-pc'.
 (Commands from memory).
 You might need to mount the root fs and chroot into it.

 I had a look at the boot console using the command you mentioned
 and nothing was unusual:

 File system:         /dev/wd0a
 Boot options:        timeout 5, flags 0, speed 9600, ioaddr 0, console pc

 I also hooked up an rs-232 cable and terminal to com0 to see if anything
 was output.  It was silent.

 Also, hooked up the HDD LED and there was absolutely no disk activity
 after:

  NetBSD MBR boot
  NetBSD/x86 ffsv2 Primary Bootstrap
  [silence]

 I'm wondering if bootstrap being confused by the SATA channels (which have
 no disks).  Maybe starting off with the PATA interface (where the disk is)
 then thinking to use the SATA later in the boot process ???

 Are you sure of that? It is still doing I/O via the BIOS until the
 kernel gets started; while I'd expect it to be using LBA for that, the
 entire problem could be that it isn't.

 It will be doing bios requests - probably as CHS requests, but the
 data it has requests a logical sector number which is converted
 to CHS using the parameters obtained from the bios that boot.
 Those ought to match!
 'sysctl machdep.diskinfo' will show the bios geometries.

 The mbr will read the pbr using the CHS values saved by fdisk.
 If fdisk were run on a different system they are very likely to
 be wrong - which is when mbr_lba can help somewhat.

  It will be doing bios requests - probably as CHS requests, but the
  data it has requests a logical sector number which is converted
  to CHS using the parameters obtained from the bios that boot.
  Those ought to match!
  'sysctl machdep.diskinfo' will show the bios geometries.

  The mbr will read the pbr using the CHS values saved by fdisk.
  If fdisk were run on a different system they are very likely to
  be wrong - which is when mbr_lba can help somewhat.

 Generally at printfs :-)
 I think there is one at the start of /boot (unless someone removed it).
 Since you aren't seeing that, something must be going on in the bootxx code.
 bootxx only has access to 'print string' and 'print value' functions,
 but they are usually enough.

 I'd make sure there are no 'clear screen' calls, then output somthing
 just before bootxx jumps into /boot, and something right at the top
 of /boot.

 Might be a size issue...
 Maybe some of the memory areas used contain bios data (I've NFI how
 to find out which areas are actually usable while you still want
 to make bios calls).

 If you suspect bios issues, can be worth using the direct serial
 console versions of stuff - in particular the code can then write
 from 32bit mode without having to switch to 16bit code for the
 bios call.

 More info on this:

 SUSE Linux 10.1 [2006] installs and works on this machine.

 Vista Anytime upgrade fails saying APCI is not compatible.

 Points to the problem?
