This PCI PATA controller can use 3V parallel flash upto 128kB. My card was identified as: PCI 1283:8212, subsystem 1283:0001.
and labelled as: Innovision Multimedia LTD. EIO ATA133 RAID (DM-8401 Ver A) This particular card did not require setting of any GPIO signals to enable flash writing. My card has Pm39LV512 in PLCC32 package without socket.
