Not really, if someone says memory stick and means a USB thumbdrive or
similar then they are providing misleading information.

There are many makers of memory sticks - licened and unlicensed, and
there are also many types of it (I think that the variety of them takes
about half of the formats on the 20something in one reader I have)

I wouldn't say 'providing misleading information' as that gives the
impression of deliberate disception. "memory stick" is as good a description
as "thumbdrive" and a lot mare accurate as it's neither a thumb or a drive.

http://wiki.answers.com/Q/What_other...flash_drive%27

See number two on the list?

Now if it'd been capitalised as Larry wrote it then one would expect that it
were a Sony format.

Lawyering again for Larry D'Loser? Fact is, to all but the hopelessly
pedantic, "memory stick" , "thumb drive", and "flash drive" are generic
terms for NAND-type flash memory devices with a USB interface. If your
client is getting paid by Sony to shill a particular brand name, tell him to
take it elsewhere.

Its a per computer licence....not per disk as far as I can tell.

Add another drive internally? Solaris can be very picky on
hardware....a way round it is to boot VMware's esxi off a 2gb usb key
and install solaris as a virtual machine...you will need a second MS
based computer to do this though. However Vmware ESXi is also picky on
sata controllers and NICs....so it depends on your hardware...

In my case the BIOS setting for USB is only active if the USB device is
connected and may be bootable..

There are two aspects to look for:

1. Characteristics of the computer's BIOS. There are two
possibilities:
a. If the machine is too old the BIOS may not have the capability.
b. There are two ways of formatting a USB stick or similar device:
i. Like a floppy - there is a boot sector at 0 followed immediately
by a FAT, then root directory.
ii. Like a hard disk - with a MBR and PT followed by (usually) a
single FAT16 or FAT32 partition. There is no theoretical reason why
multiple partitions cannot be used, or alternative file systems such
as NTFS, ext2, ext3, etc. It is possible that non FAT file systems
may impede operation of wear spreading algorithms.

Some BIOS's are fussy and do not like i or ii, I think that i is the
generally disliked one.

2. Assuming 1. is overcome, the stick must actually be bootable.
This requires:
a. Appropriate booting code on the MBR as found on a normal HD. USB
stick MBR's do not necessarily have this code, so it needs to be
'installed' by some means or other.
b. The partition may need to be declared 'bootable' in its partition
table (PT) entry (usually done with 'fdisk' or similar software.
c. Similarly for the boot sector needs to have appropriate boot code.

Information sources on how to do this seem to be chaotic - I am
unaware of the existence of a simple 'Howto' on this.

Hope this helps.

Good luck!

Surely either the BIOS supports booting from USB storage devices or it
doesn't.

In either case, there is bootloader code in sector 0 to be loaded into RAM
and jumped to, which is all the BIOS needs to know. The BIOS knows nothing
about partitioning or filesystems.

I don't see how. In any case, wear-spreading operates at the sector level.

It turns out there is one difference, namely whether the drive firmware
indicates that the drive is "fixed" or "removable"
<http://www.boot-land.net/forums/?showtopic=4560>. "Fixed" devices are
treated as hard drives, "removable" ones like floppies.
