FLASH EPROM Programming
To program a Flash device in byte-wide socket S0, use the FlashWRI.EXE utility supplied on the
Common Utilities diskette. The Common Utilities manual describes its operation. Only devices
with 5V programming power are supported.
Custom Flash-programming routines can be developed using extended BIOS calls in the ROM
BIOS. Contact Ampro Technical Support for information about the extended BIOS call provided for
Flash programming power.
