 Posted: Thu Jun 07, 2012 5:04 am Post subject: Help identifying PROM chip |
 |
|
| I'm trying to identify the "EVEN" BIOS chip in the attached photo (the one without the label sticker) - I'm guessing it's a 128K OTP EPROM, but I'm secretly hoping it's an "after-market" EEPROM of at least 512K, so that I can easily use it to test another 286 board... |

Yes, I have this board, but without the BIOS chip, I found two BIOS images on some Russian sites, and I'm looking for a way to test the board without having to chase EPROMs, UV-erasers and programmers (basically I'm looking for a large enough DIP-28 chip that can be UNIFLASHed  ):

| I haven't seen many 286 boards using 512K BIOS chips... plus, you're way too far from me . |
