We + * try to request it here, but if it fails, we carry on anyway. + * + * This is how the chip is attached, so said the schematic: + * * a 4 MiB (32 Mib) 16 bit chip + * * a 1 MiB memory region + * * A20 and A21 pulled up + * * D8-D15 ignored + * What this means is that, while we are addressing bytes linearly, we are + * really addressing words, and discarding the other byte. This means that + * the chip MUST BE at least 2 MiB. This also means that every block is + * actually half as big as the chip reports. It also means that accesses of + * logical address 0 hit higher-address sections of the chip, not physical 0. + * One can only hope that these 4MiB x16 chips were a lot cheaper than 1MiB x8 + * chips. + * + * This driver assumes the chip is not write-protected by an external signal. + * As of the this writing, that is true, but may change, just to spite me. + * + * The actual BIOS layout has been mostly reverse engineered. Intel BIOS + * updates for this board include 10 related (*.bio - &.bi9) binary files and + * another separate (*.bbo) binary file. The 10 files are 64k of data + a + * small header. If the headers are stripped off, the 10 64k files can be + * concatenated into a 640k image. This is your BIOS image, proper. The + * separate .bbo file also has a small header. It is the 'Boot Block' + * recovery BIOS. Once the header is stripped, no further prep is needed. + * As best I can tell, the BIOS is arranged as such: + * offset 0x00000 to 0x4ffff (320k): unknown - SCSI BIOS, etc? + * offset 0x50000 to 0xeffff (640k): BIOS proper + * offset 0xf0000 ty 0xfffff (64k): Boot Block region + * + * Intel's BIOS update program flashes the BIOS and Boot Block in separate + * steps.
