Hi. I want to use Busmaster mode with my NOTE-PC and 3.1-RELEASE. I have NOTE-PC which has: NEC MobioNX PCI Chipset: Opti FineStarPlus(82C700) HDD: IBM-DDLA-21620 (PIO Mode-4, Multiword DMA Mode-2) I read Datasheet of FineStar Plus. It support Bus Master IDE HDD. But if I test with flags 0x2000 or 0xa0ff with wdc0, I can't use it. At change root device to wd0s1a, hung-up and light HDD access LED. I think that BIOS is not set some timing of IDE Controller and it is needed to some code of opti_dmainit and opti_status in /sys/pci/ide_pci.c. I read CVS log of ide_pci.c. >It runs on my P6 natoma board with two Maxtor drives, and also >on a Fujitsu machine I have at work with an Opti chipset and >a Quantum drive. Does someone imprement BusMaster capable code for Opti Chip? Thank you MIHIRA Yoshiro To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
