Seems that this tablet has GT9110 chip with custom firmware. Here is dump of config data: 0x8040: xx xx xx xx xx xx xx 4e b0 04 80 07 0a 05 20 01 0x8050: c8 1e 05 41 2d 03 00 00 00 00 00 00 00 00 00 00 0x8060: 00 00 95 35 ff 14 16 e5 26 03 07 00 1b 03 11 00 0x8070: 00 00 00 0b 0f 07 12 03 00 00 0a 1e 54 c0 04 00 0x8080: 00 00 04 c3 0b 00 ac 0d 00 8e 11 00 7c 15 00 6d 0x8090: 1b 00 6c 00 00 00 00 00 00 00 00 00 00 00 00 00 0x80a0: 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 20 0x80b0: 00 00 00 00 00 50 00 1d 1c 1b 1a 19 18 17 16 15 0x80c0: 14 13 12 11 10 0f 0e 0d 0c 0b 0a 09 08 07 06 05 0x80d0: 04 03 02 01 00 2a 29 28 27 26 25 24 23 22 21 20 0x80e0: 1f 1e 1d 1c 1b 19 18 17 16 15 14 13 12 11 10 0f 0x80f0: 0e 0d 0c 0b 0a 09 08 07 06 05 04 03 02 01 00 fe 0x8100: 00 0x8140: 39 31 31 30 03 20 b0 04 80 07 00 00 00 04 I didn't find any way to reliable detect of format using only the config data, so DMI check for machine name is used.
