 Second test
 
 I did procedure "Initializing and using USB flash drives" from NetBSD Guide=
  to create MSDOS partition on USB stick.
 Then I started NetBSD 8.0 installation but the installation finished with m=
 essage "Rewrite of MBR failed. I can't continue."
 Then I started NetBSD 9.0_RC1 installation but there still is size of USB s=
 tick 232 MB and there are no screens to set MBR partitions.
 Results of fdisk and disklabel at the end.
 
 Details bellow:
 
 Initializing and using USB flash drives
 1. dd if=3D/dev/zero of=3D/dev/rsd0d bs=3D1m count=3D1
 2. fdisk -au sd0
    Do you want to change our idea of what BIOS thinks? [n]
    Which partition do you want to change?: [none]0
    sysid: [0..255 default: 169]11
    Do you want to change the active partition? [n]y
    active partition: [0..4 default: 4]0
    Are you happy with this choice? [n]y
    Should we write new partition table? [n]y
 3. newfs_msdos /dev/rsd0e
 
 Installation of NetBSD 8.0
 1. Install NetBSD to hard disk
 2. Shall we continue? Yes
 3. sd0 (929M, SONY WALKMAN)
 4. The phisical geometry is 471 cylinders 16 sectors 63 heads
    sectors [63]:Enter
    heads   [16]:Enter
 5. Use the entire disk
 6. Do you want to install the NetBSD bootcode? Yes
 7. Set sizes of NetBSD partitions
 8. a:
    Size for / in MB?[33+]:800
    b:
    Size for swap in MB? [893]:0+
    x: Accept partition sizes
 9. Partition sizes ok
 10. Please enter a name for your NetBSD disk [WALKMAN   ]:Enter
 11. Shall we continue? Yes
     Rewrite of MBR failed. I can't continue.
     Hit enter to continue
 
 Installatin of NetBSD 9.0_RC1
 1. Install NetBSD to hard disk
 2. Shall we continue? Yes
 3. On which disk do you want to install NetBSD?
    b: sd0 (929M)
 4. The phisical geometry is 471 cylinders 16 sectors 63 heads
    sectors [63]:Enter
    heads   [16]:Enter
 5. Set sizes of NetBSD partitions
    i: Change input units (sectors/cylinders/MB/GB)
    b: Megabytes
    a:
    Would you like to delete this partition and continue ?
    a: Yes
    Size for / in MB?[0]:200
    b:
    Size for in MB?[232]:0+
 8. x: Go on.
 9. Partition sizes ok
 10. Shall we continue? Yes
 11. Selected bootblock: BIOS console
     x: Continue
 12. x: Abandon installation
