After reading some mail about HDPARM, I'd to know the state of my HD according to the coniguration of my LINUX BOX
__BIOS SETTINGS__
Primary Master
Type Auto LBA/Large Mode on Block Mode on 32bit Mode on PIO Mode 4
__KERNEL__
ide: i82371 PIIX (Triton) on PCI bus 0 function 57 ide0: BM-DMA at 0xffa0-0xffa7 ide1: BM-DMA at 0xffa8-0xffaf hda: IBM-DJAA-31700, 1628MB w/96kB Cache,LBA, CHS=827/64/63 hdb: ACER CD-767E/O, ATAPI CDROM drive
__XCONFIG__
* General Setup
PCI bios support y System V IPC y Kernel support for ELF binaries y Processor type Pentium
* Floppy,IDE, and other block devices
Enhanced IDE/MFM/RLL disk/cdrom/tape support y CMD640 chipset bugfix/support y CMD640 enhanced support y RZ1000 chipset bugfix/support y Intel 82371 PIIX DMA Support y
__STATE__
/dev/hda:
Model=IBM-DJAA-31700, FwRev=P0IRA72D, SerialNo=1P51P128 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=3308/16/63, TrkSize=0, SectSize=0, ECCbytes=16 BuffType=3(DualPortCache), BuffSize=96kB, MaxMultSect=16, MultSect=off DblWordIO=no, maxPIO=2(fast), DMA=yes, maxDMA=2(fast) CurCHS=3308/16/63, CurSects=3334464, LBA=yes, LBAsects=3334464 tDMA={min:120,rec:120}, DMA modes: sword0 sword1 sword2 mword0 mword1 mword2 IORDY=on/off, tPIO={min:200,w/IORDY:120}, PIO modes: mode3 mode4

************** hdparm -t -f /dev/hda
/dev/hda: Timing buffered disk reads: 16 MB in 3.75 seconds = 4.27 MB/sec ^--- The Best Value __IMPROVING(?)__
************** hdparm -m16 -c3 -X12 /dev/hda
/dev/hda: setting 32-bit I/O support flag to 3 setting multcount to 16 setting xfermode to 12 (PIO flow control mode4) multcount = 16 (on) I/O support = 3 (32-bit w/sync)
/dev/hda: Timing buffer-cache reads: 32 MB in 1.04 seconds =30.77 MB/sec
/dev/hda: Timing buffered disk reads: 16 MB in 3.37 seconds = 4.75 MB/sec ^-- Medium Value /dev/hda:

/dev/hda: multcount = 16 (on) I/O support = 3 (32-bit w/sync) unmaskirq = 0 (off) using_dma = 0 (off) ^-the options -d1 -X34 decrease performance to 3.75MB/sec keepsettings = 0 (off) ^^^^^^ nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 827/64/63, sectors = 3334464, start = 0
__QUESTIONS__
1)Why don't Linux use the Bios settings ? 2)Why -d1 -X34 decrease ? 3)How to set -m16 -c3 -X12 to HD finally ?
