機器很古老大概只有 P3 而已若想裝大硬碟 ex 500G 這種都是以 SATA 居多不得不用外接卡想問一下 FreeBSD 對 SATA 卡的支援度好媽？ man ata 找到這些 ---------------- The ata driver provides access to ATA (IDE) and SerialATA disk drives, ATAPI CDROM/DVD drives, ZIP/LS120 ATAPI drives and ATAPI tape drives con- nected to controllers according to the ATA/ATAPI standards. The currently supported ATA/SATA controller chips are: Acard: ATP850P, ATP860A, ATP860R, ATP865A, ATP865R. ALI: M5229, M5281, M5287, M5289. AMD: AMD756, AMD766, AMD768, AMD8111. ATI: IXP200, IXP300, IXP400. CMD: CMD646, CMD646U2, CMD648, CMD649. Cypress: Cypress 82C693. Cyrix: Cyrix 5530. HighPoint: HPT302, HPT366, HPT368, HPT370, HPT371, HPT372, HPT372N, HPT374. Intel: 6300ESB, 31244, PIIX, PIIX3, PIIX4, ESB2, ICH, ICH0, ICH2, ICH3, ICH4, ICH5, ICH6, ICH7, ICH8. ITE: IT8211F, IT8212F. JMicron: JMB360, JMB361, JMB363, JMB365, JMB366. Marvell 88SX5040, 88SX5041, 88SX5080, 88SX5081, 88SX6041, 88SX6081. National: SC1100. nVidia: nForce, nForce2, nForce2 MCP, nForce3, nForce3 MCP, nForce3 Pro, nForce4.

ServerWorks: HT1000, ROSB4, CSB5, CSB6. Silicon Image: SiI0680, SiI3112, SiI3114, SiI3512.

VIA: VT6410, VT6420, VT6421, VT82C586, VT82C586B, VT82C596, VT82C596B, VT82C686, VT82C686A, VT82C686B, VT8231, VT8233, VT8233A, VT8233C, VT8235, VT8237, VT8237A, VT8251. Unknown ATA chipsets are supported in PIO modes, and if the standard bus- master DMA registers are present and contain valid setup, DMA is also enabled, although the max mode is limited to UDMA33, as it is not known what the chipset can do and how to program it. The ata driver can change the transfer mode and various other parameters when the system is up and running. See atacontrol(8). The ata driver sets the maximum transfer mode supported by the hardware as default. However the ata driver sometimes warns: ``DMA limited to UDMA33, non-ATA66 cable or device''. This means that the ata driver has detected that the required 80 conductor cable is not present or could not be detected properly, or that one of the devices on the channel only accepts up to UDMA2/ATA33. Unknown ATAPI devices are initialized to DMA mode if the hw.ata.atapi_dma tunable is set to 1 and they support at least UDMA33 transfers. Other- wise they are set to PIO mode because severe DMA problems are common even if the device capabilities indicate support. You can always try to set DMA mode on an ATAPI device using atacontrol(8), but be aware that your hardware might not support it and can potentially hang the entire system causing data loss. ----------------------------- 看完不是很懂尤其是最後兩段感覺上是支援這些晶片但最多只能跑 ATA66 ??? hw.ata.atapi_dma 不太清楚是幹麻的~ 原文有畫底線可能很重要吧@@? 我有另外去看 hardware note (我的OS是 6.2 RELEASE) Driver 有支援的SATA 好像又都不是這種我的用途：單純為了擴充硬碟不會用到RAID 我想問的問題是 1.SATA卡系統真的認識它因為 hardware note 裡面只有列出那些很貴的卡....LSI 3Ware 我太窮了買不起 >< 找了一些比較便宜的卡 ex: HighPoint RocketRAID 1520 1720 1640 雖然 hareware note 沒有列但是HighPoint 官方有放 BSD 的Driver 其他家公司做的我就都沒有看到所以也就沒有考慮 2.買了能跑的出他的效果嗎？ (就是跑150 or 300) 還是真的如同上面所說就是跑 ATA33 最多 ATA66 這樣？ ==== 研究了好久沒有頭緒很怕買了跑不出預期的效果那不如等IDE 但SATA已經是市場主流要是大容量不做IDE 最後還是要遷就 SATA Orz 很困惑請大家幫忙推薦一下吧 ^^||| 謝謝~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 163.13.127.194
