Well, you can find it from dmesg, just grep for hd? (for whatever IDE device
you're looking for). Mine reports:
PIIX4: IDE controller on PCI bus 00 dev 39
PIIX4: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
hda: FUJITSU MPD3130AT, ATA DISK drive
hdb: Hewlett-Packard CD-Writer Plus 7500, ATAPI CDROM drive
hdc: IOMEGA ZIP 100 ATAPI, ATAPI FLOPPY drive
hdd: CD-532E, ATAPI CDROM drive
You should also be able to get this from hdparm -i /dev/hd? (as above).
Again, here is the report from my workstation:
/dev/hda:
Model=FUJITSU MPD3130AT, FwRev=DD-04-47, SerialNo=01009599
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=0(?), BuffSize=512kB, MaxMultSect=16, MultSect=off
DblWordIO=no, OldPIO=2, DMA=yes, OldDMA=0
CurCHS=16383/16/63, CurSects=-66060037, LBA=yes, LBAsects=25431840
tDMA={min:120,rec:120}, DMA modes: mword0 mword1 mword2
IORDY=yes, tPIO={min:120,w/IORDY:120}, PIO modes: mode3 mode4
UDMA modes: mode0 mode1 *mode2
Look for BuffSize in there, that's the cache size. HTH,
