You need a separate EPROM programmer. I am not jumpimg on you , I just don't want to start another arguement here, so just take my word for it, Stepen is absolutly right and I can do this. See the a previous message I wrote to him The motherboard will use EITHER an EPROM or an EEPROM and can be programmed on the MB. I have the software and the program that will remove the SCSI from the BIOS. All I have to do is change a jumper to do the programming. However, I cannot reprogram an EPROM on the MB, I have to use an EPROM programmer to do that. I can Hot Swap the EPROM with an EEPROM and do it. Most of the 486 class motherboard I have run across can use either an EPROM or EEPROM. Various OEM could chose either one. Some OEMs used both types for various vendors according to their spcifications. For example, if gateway should want to use this particular MB, they would put thier own BIOS in it and chose whether to use an EPROM or an EEPROM. Many of these type of boards were used by many manufactures and they all would use thier own BIOS developed by AMI, AAWARD, Phoenix, Mr BIOS, or their own such as Magnavox used what they call NAPA (the name of their parent company.) I do not care if anyone believes me or not. If you want to buy me an EEPROM and come visit me, I'll do it right in front of your eyes. Also my Motherboard is not unique. My bother has a 5x86-133 M-6119 that can also use either an EPROM or and EEPROM. There are jumpers for it. Our problem with his board, is that we cannot determine the manufacture to see if a BIOS update is available. There quite a few OEMs that used this board and AMI's references show mnay OEMs that used it and cannot seem to narrow it down. There is no FCC indetification on his MB and I have downloaded numerous schematics and board layouts and have not been able to match one up yet. Several of these OEM do not have info available for their M-6119 boards on the WEB. He really needs an update for it. I don't really have to have one for mine. It would be nice, but not like he needs one for his.
