About Grains BIOS Repair-est. 2006

We are actively engaged in repairing Flash BIOS for PC's, Laptops, and other equipment that use a Flash ROM type chip or EEPROM.

Stock consists of mainly SPI Serial Flash, PLCC, DIP, VSOP and TSOP EEPROM. We have SPI Serial Flash chips in both SOIC and PDIP in stock. We are able to offer a Worldwide chip programming service.

Qualified Marine Electrical Fitter, time served with sea going experience. City and Guilds in Electrical and Electronic Craft studies gained in Falmouth marine college (Cornwall) and Rhymney technical College Cardiff  between 1971 and 1975.

Device Programming

We are able to program many different Devices such as 8 Pin SPI Serial Flash in both SOIC and PDIP, PLCC EEPROM's, and also 32, 40 48 pin and 56 pin TSOP/VSOP types. We are currently expanding the range SPI devices that we stock.

We currently stock SST, Winbond, EON, Intel, cFeon and Macronix devices. Other EEPROM types would require additional adapter's, our programmers will burn most types of EEPROM and adapters are purchased as and when the need arises.

EEPROM's

We stock a good range of Brand New PLCC, DIP, PDIP, TSOP, VSOP and SPI Flash types.. Parts are normally added to stock based on the number of customer inquiries we receive for any particular part.

If we receive a lot of requests for a part that is not in stock, we will consider stocking it and adding the chip to the range of available EEPROM's that we currently stock.
Additions are made on a regular basis, and we do try to keep the parts mentioned on the EEPROM page in stock. Usually parts are re ordered before we run out entirely. Older parts are being replaced with modern lead free types where possible....
