Greetings all, I’m a new OpenBSD user so I’m assuming my issues are lack of knowledge and was hoping to get little help.
Overview: I have installed Maxtor ATA 133 PCI card with a Promise PDC20269 chipset in my Sun Ultra 5. Using the clues found here https://www.netbsd.org/ports/sparc64/faq.html#pci-cards I was able to define the vendor class code by finding the PCI card in openboot show-devs cd /pci@1f,0/pci@1/<DEVICE> .properties the class-code my Promise PDC20269 is 00018085 nvedit dev /packages/SUNW,builtin-drivers : class018085 f 9 my-space + " config-b!" $call-parent class010100 ; device-end This gives a proper ide@2 device with disk and cdrom children. So I moved my cable from the internal IDE devices to pci card created a new devlias and booted directly via the card.. So far so good. Problem: The problem is the DMESG shows the PIO MODE 4, Ultra-DMA mode 2 so there is no performance gain, using the atactl wd0 identify is shows me the drive is capable of UDMA 7. Question: How can I increase the DMA Mode, or is this indicate something else is wrong? Thanks for any advice. -Mike
