2.8.2 ISA-Incompatibilitiy with ISA-PCCARD-Controller
The experience is, that ATA-Drives controlled in a ISA-PCMCIA Controller are not working.
Solution:
Using a PCCARD-Controller on the PCI-Bus
2.8.3 ISA-Incompatibilitiy with 16Bit I/O Transfer with FPGA-Decoder
The experience is, that 16Bit I/O-transfers decoded with a FPGA are not allways working correct. Each case
must be tested. Specially on odd adresses are problems expected.
Solution:
Using two 8Bit transfer instead one 16Bit transfer. For timecritical transfers is recommended to use the PCI-
Bus.
2.8.4 ISA-Incompatibilitiy with 16Bit Memory Transfer with FPGA-Decoder
The experience is, that 16Bit Memory-transfers decoded with a FPGA are not allways working correct. Each
case must be tested. Specially on odd adresses are problems expected.
Solution:
Using two 8Bit transfer instead one 16Bit transfer. For timecritical transfers is recommended to use the PCI-
Bus.
