DIGI-KEY Part No. SST39SF040-70-4C-PHE
IC FLASH MPF 4MBIT (512KBYTES) 70NS 32DIP


This is flashing using a Tyan S1832DL board
00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03)
...
00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 02)

(... am I getting this right, flashrom uses the ISA bridge to write to flash part?)
