2.9.2.
ISA-Incompatibility with ISA-PCCARD-Controller
Experience shows that ATA-Drives controlled in an ISA-PCMCIA Controller do not work.
Solution: Use a PCCARD-Controller on the PCI-Bus
2.9.3.
ISA-Incompatibility with 16bit I/O Transfer with FPGA-Decoder
Our experience shows that 16bit I/O-transfers decoded with a FPGA do not always work correctly. Each
case must be tested. Expect problems on odd addresses.
Solution: Use two 8bit transfers instead of one 16bit transfer. For time critical transfers we recommend
using the PCI-Bus.
2.9.4.
ISA-Incompatibility with 16bit Memory Transfer with FPGA-
Decoder
Experience shows that 16bit Memory-transfers decoded with a FPGA do not always work correctly. Each
case must be tested. Expect problems on odd addresses.
Solution: Use two 8bit transfers instead of one 16bit transfer. For time critical transfers we recommend
using the PCI-Bus.
