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.

This PCI PATA controller can use 3V parallel flash up to 128 kB.
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.
