Hello,
Is there someone able to tell how the checksum of the Ethernet Station
Address ROM is calculated? This is the ROM layout with 'ba' being the
base address of the ROM:
0xba02 addres octet 0
0xba06 addres octet 1
0xba0a addres octet 2
0xba0e addres octet 3
0xba12 addres octet 4
0xba16 addres octet 5
0xba1a checksum octet 1
0xba1e checksum octet 2
0xba22 checksum octet 2
0xba26 checksum octet 1
0xba2a addres octet 5
0xba2e addres octet 4
0xba32 addres octet 3
0xba36 addres octet 2
0xba3a addres octet 1
0xba3e addres octet 0
0xba42 addres octet 0
0xba46 addres octet 1
0xba4a addres octet 2
0xba4e addres octet 3
0xba52 addres octet 4
0xba56 addres octet 5
0xba5a checksum octet 1
0xba5e checksum octet 2
0xba62 test pattern 0 ff
0xba66 test pattern 1 00
0xba6a test pattern 2 55
0xba6e test pattern 3 aa
0xba72 test pattern 4 ff
0xba76 test pattern 5 00
0xba7a test pattern 6 55
0xba7e test pattern 7 aa
With the two machines here having the following values:
5000/25 5000/133
addres octet 0: 08 08
addres octet 1: 00 00
addres octet 2: 2b 2b
addres octet 3: 30 2f
addres octet 4: 8d 06
addres octet 5: 2b ca
checksum octet 1: 03 7d
checksum octet 2: 8c 28
Regards,
Richard
