(g) determining if said first gaming device has been idle for at least a designated amount of time;

(h) transmitting said software to a programmable memory in said first gaming device and third information identifying said software from said source to said first gaming device when said first gaming device has been idle for at least said designated amount of time; and

(i) storing said third information identifying said software in a second memory location of said one-time programmable or add-only memory of said first gaming device in association with said software and wherein said third information stored in said second memory location cannot be changed or erased.

2. The method of claim 1, which includes:

calculating a signature based at least partially on a random starting address and transmitting said signature to said source; and

comparing said signature with a signature available to said source.

3. The method of claim 1, which includes repeating (g) when said first gaming device has not been idle for said designated amount of time.

4. The method of claim 1, which includes repeating (g) after a predetermined time period when said first gaming device has not been idle for said designated amount of time.

5. The method of claim 1, wherein the designated amount of time is based on the time between wagers made by a player.

6. The method of claim 1, wherein the designated amount of time is based on the time between handle pulls by a player.

7. The method of claim 1, which includes transmitting the software in a blockwise sequence.

8. The method of claim 1, wherein said first information includes information identifying software stored on said first gaming device and further includes at least one of serial or other hardware identification numbers, manufacturing ID information or codes, manufacturer name, hardware or software revision designations, date of manufacture, date of installation, date of sale, date of shipping, date of software revision and software file size.

9. The method of claim 1, wherein said second information includes information identifying software stored on said source and further includes at least one of a board serial number, a board version number, a clock speed, a processor type, a software indicator, a software version number, a date of assembly, and an indicator of gaming regulatory jurisdiction.

10. The method of claim 1, wherein said third information includes at least one of a software indicator, a software revision designation, date of software revision, software file size, and an indicator of gaming regulatory jurisdiction.

11. The method of claim 1, wherein said first gaming device includes a plurality of circuit boards, and wherein said source is coupled to a first of said circuit boards and wherein said first information identifies hardware on at least a second of said circuit boards.

12. The method of claim 1 wherein said first gaming device includes a plurality of circuit boards which contain a non-programmable memory storing hardware identification information.

13. The method of claim 1, wherein transmitting said software from said source to said first gaming device uses a serial data transmission protocol.

14. The method of claim 1, further comprising:

transmitting fourth information from said second gaming device to said source, said fourth information identifying at least a second hardware component of said second gaming device;

comparing said fourth information to predetermined fourth information to determine whether said software is appropriate for said at least second hardware component of said second gaming device; and

determining that the software is not appropriate for said at least second hardware component of said second gaming device.

15. The method of claim 14, wherein the steps after the verifying step are not performed with respect to the second gaming device.

16. An apparatus for downloading software from a source to a gaming device, the apparatus comprising:

a processor and programming to carry out the steps of;

accessing first information in a first memory location of a one-time programmable or add-only memory of said gaming device, said first information identifying at least a first hardware component of said gaming device and wherein said first information stored in said first memory location cannot be changed or erased;

transmitting said first information to said source;

identifying said at least first hardware component with reference to said first information received from said gaming device;

verifying, based on said first information, that said software is appropriate for said at least first hardware component based on the gaming jurisdiction in which the gaming device is located;

transmitting second information from said source to said gaming device describing at least a first characteristic of said software and a request for an approval response;

verifying that said gaming device is in a ready mode by determining if said gaming device has current credits granted;

transmitting the approval response from said gaming device to said source indicating that said gaming device is configured to receive said download;
