Hello,
To move a compiled system and kernel to other, smaller device I produce
so called memsticks which are made with the script
/usr/src/release/amd64/make-memstick.sh
They do, i.e. booting fine and showing for example on a netbook Acer C720 in
/var/log/messages on attach:
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0 at umass-sim0 bus 0 scbus1 target 0 lun 0
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0: <Ut165 USB2FlashStorage 0.00> Removable Direct Access SCSI-2 device
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0: Serial Number 09022100003131
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0: 40.000MB/s transfers
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0: 7712MB (15794176 512 byte sectors)
Jun 7 10:35:43 c720-r292778-amd64 kernel: da0: quirks=0x2<NO_6_BYTE>
wnd with FDISK:
$ fdisk da0
******* Working on device /dev/da0 *******
parameters extracted from in-core disklabel are:
cylinders=983 heads=255 sectors/track=63 (16065 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=983 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 238 (0xee),(EFI GPT)
start 1, size 14683749 (7169 Meg), flag 0
beg: cyl 0/ head 0/ sector 2;
end: cyl 1023/ head 255/ sector 63
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
If I use the fine memstick on some other laptop, in this case a Dell
Latitude E6330, it just says 'Invalid partition table!'
What could be wrong with it?
