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.
