Now I understand the problem much better. I plan to redraw the info structure in full big endian and to perform the correct translation (both 16 bit word byte swap and 32 bit word full swap) one for all in read_pio. I'll have a patched version in the next few days. Cheers,

I was the whole week in a Juniper training in Holland and had not been able to test this new driver. I just done it today. Here is the syslog output I've got when doing 'insmod eata.o' or 'insmod eata.o io_port=0x1410' : Jun 15 14:43:50 brocoli kernel: PCI: Enabling device 00:0f.0 (0014 -> 0015) Jun 15 14:43:50 brocoli kernel: EATA: detect, seq. 0, bus 0, devfn 0x78, addr 0x1400. Jun 15 14:43:50 brocoli kernel: EATA0: warning, weird ISA board not using DMA. Jun 15 14:43:50 brocoli kernel: EATA0: warning, DMA protocol support not asserted. Jun 15 14:43:50 brocoli kernel: EATA0: warning, LEVEL triggering is suggested for IRQ 3. Jun 15 14:43:50 brocoli kernel: EATA0: unable to allocate IRQ 3, detaching. The module does not load and the card hangs (the two extreme leds lid up). For reference the lspci -vv output after that is : 00:0f.0 SCSI storage controller: Distributed Processing Technology SmartCache/Raid I-IV Controller (rev 02) Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (1000ns min, 2000ns max), cache line size 08 Interrupt: pin A routed to IRQ 25 BIST result: 00 Region 0: I/O ports at 1400 [size=32] Expansion ROM at 80908000 [disabled] [size=32K] As the IRQ number is not the same, I tried a dirty quick hack in the code to set it to 25. Here is the output of 'insmod eata.o io_port=0x1400' afterward : Jun 15 16:12:14 brocoli kernel: EATA: enable_pci_ports, bus 0, devfn 0x78.

And then insmod and the card are hanging... with no other possibility than a reboot. I suppose the 4 bits in eata_info for the IRQ should be translated to something else ... but in what ? I also suppose there are other thing in this struct that have to be translated. I'll try to print the whole eata_info struct if I have time tomorrow or monday. If you have other suggestions or improvements, they are welcomed. Have a nice week-end ! Antoine.
