I cleaned out the thread, leaving only your last bit of questions here.
I did apparently screw up the 'dd' cmd, I retyped it correctly, below is my
(very carefully) retyped recreation of the Fixit prompt;
[..]
Fixit# dd if=/dev/zero of=/dev/ad4 oseek-0 bs=512 count=1
1+0 records in
1+0 records out
512 bytes transferred ub 0.044723 secs (11448 bytes/sec)
Fixit# fdisk -Bi /dev/ad4
******* Working on device /dev/ad4 *******
parameters extracted from in-core disklabel are:
cylinders=1453521 heads=16 sectors/tracks=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1453521 heads=16 sectors/tracks=63 (1008 blks/cyl)
Do you want to change our idea of what BIOS thinks ? [n]
[..]
This is where I stopped, admittedly, I do not know how to use FreeBSD's
fdisk. For the sake of brevity and to move along, I'll break fdisk here and
move back to sysinstall and provide what information I can this way.
>From sysinstalls menu, I choose 'Standard', next is the usual message about
fdisk partitioning schemes. After this, I get a 'User Confirmation Request',
which is very similar to the warning I received above. It says
[..]
WARNING: It is safe to use a geometry of 1453521/16/63 for ad4 on computers
with modern BIOS versions. If this disk is to be uised on an old machine it
is recommended that it does not have more then 65535 cylinders, more then
255 heads, or more then 63 sectors per track.
Would you like to keep using the current geometry?
<Yes> <No>
[..]
This is where I have two choices
Choice 1 (YES) produces the following in fdisk when choosing 'a' to use the
whole disk.
[..]
Offset Size(ST) End Name PType Desc Subtype
Flags
0 63 62 - 12 unused 0
63 1465149105 1465149167 ad4s1 8 freebsd 165
[..]
Choice 2 (NO) produces the following in fdisk when choosing 'a' to use the
whole disk.
[..]
If you are not sure about this, please consult the Hardware Guide in the
Documentation submenu or use the {G}eometry command to change it. Remember:
You need to eneter whatever your BIOS thinks the geometry is! For IDE, it's
what you were told in the BIOS setup. For SCSI, It's the translation mode
your controller is using. Do NOT use a ''physical geometry''.
<OK>
[..]
[..]
Offset Size(ST) End Name PType Desc Subtype
Flags
0 63 62 - 12 unused 0
63 1465144002 1465144064 ad4s1 8 freebsd 165
1465144065 5103 1465149167 - 12 unused 0
[..]
Decidedly, the end result is approximately 698GB for the usable partition,
the second choice giving me a padding on both sides of the freebsd slice.
Moving on now, I choose the following
Standard MBR
Disklebel Editor
[..]
Part Mount Size newfs
---- ----- ---- -----
ad4s1a / 512MB UFS2 Y
ad4s1b swap 4096MB SWAP
ad4s1d /var 4973MB UFS2+S Y
ad4s1e /tmp 512MB UFS2+S Y
ad4s1f /usr 688GB UFS2+S Y
[..]
Decidedly not my first choice for 8.1/amd64, but I can fix that layout
later, once I know how to get the system installed correctly.
'Q' to quick and continue, I choose 'Minimal' then 'CD/DVD' as my
installation media. I got the usual 'Last Chance' warning and then bam, I
get
[..]
Unable to find device node for /dev/ad4s1b in /dev!
The creation of filesystems will be aborted.
<OK>
Couldn't make filesystems properly. Aborting.
<OK>
Installation completed with some errors. You may wish to scroll through the
debugging messages on VTY1 with the scroll-lock feature. You can also choose
"No" at the next prompt and go back into the installation menus to retry
whichever operations have failed.
<OK>
[..]
And this is where I am left. Hopefully, I've been explicit enough this time
:D Again, if I've missed something, please let me know and I shall provide
it.
