Difference between the ATC 1020 (Rev 1.x ?) (bios v1.1) and the ATC 1020 Rev. 2 (bios v1.3)

 

* The ATC 1020 (Rev 1.x ?) Bios v1.1 offers an undocumented support for Pentium 166-233mmx and Amd K6 166-233mmx cpus: old bios doesn't recognize correctly these cpus. This mainboard have the JP11/JP12/JP13 jumpers (three jumpers with two pins) that allow an undocumented setting for Dual voltage Cpus (mmx) and JP14 jumper that allow an undocumented setting for various type of splitted voltage.

* The ATC 1020 Rev. 2 (Bios v1.3) offers a partial documented support for Pentium 166-233mmx and Amd K6 166-233mmx cpus, but old bios doesn't recognize the AMD K6 cpus correctly. This mainboard have the JP11 jumper (one jumper with three pins) that allow a documented setting for Dual voltage Cpus (mmx) and JP14 jumper that allow a documented setting for various type of splitted voltage.For New settings, see http://www.vobis.de/vob/atrend/mb/atc1020/ll_gb.htm
*Exist however a PLUS version of the ATC-1020 (ATC-1020 PLUS) mainboard that offers full documented support for mmx cpus.

Question

Answer

The bios update is impossible !! In order to upgrade your flash eprom, you MUST set the JP19 jumper ( Boot Block Write)
