Dear List,
This is my second post since I did not receive
any answers the first time.
I have P4P800-VM motherboard with serial ata
controlers (ICH5) and serial ata discs. I managed
to install FreeBSD 4.9-STABLE on this box when
setting the IDE controller in legacy mode.
Everything works normal except when booting,
the drives are set into UDMA33 mode:
atapci0: <Intel ICH5 SATA150 controller> port
0xfc00-0xfc0f,0-0x3,0-0x7,0-0x3,0-
0x7 irq 0 at device 31.2 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
ad0: DMA limited to UDMA33, non-ATA66 cable or device
ad0: 76319MB <ST380013AS> [155061/16/63] at ata0-master UDMA33
ad1: DMA limited to UDMA33, non-ATA66 cable or device
ad1: 76319MB <ST380013AS> [155061/16/63] at ata0-slave UDMA33
I read somewhere that this message is a hoax and that
the drive should actually work in UDMA150. Is this my case?
I also checked the source of ata-dma.c:
Here is the section.
#if 1
if (udmamode > 2 && !atadev->param->hwres_cblid) {
ata_prtdev(atadev,"DMA limited to UDMA33, non-ATA66 cable or device\n");
udmamode = 2;
}
#endif
Maybe this should sound like:
if ( (udmamode > 2) && (udmamode < 5) && (!atadev->param->hwres_cblid) ) {
ata_prtdev(atadev,"DMA limited to UDMA33, non-ATA66 cable or device\n");
udmamode = 2;
}
All comments are wellcome.
Thank you in advance
