Disks on the IBM PC110

The PC110-YD comes with an internal 4Mb flash disk and a 340Mb removable PCMCIA hard disk.

The flash disk is supplied with Japanese DOS and the Personaware software installed. Under Linux, it shows up as /dev/hda with a single partition, /dev/hda1, which can be accessed just like a normal IDE device. The output of /sbin/hdparm -i /dev/hda is:


 Model=SunDisk SDP3B-4, FwRev=Rev 1.20, SerialNo=MZX00045
 Config={ HardSect NotMFM Removeable DTR>10Mbs nonMagnetic }
 RawCHS=123/2/32, TrkSize=0, SectSize=576, ECCbytes=4
 BuffType=2(DualPort), BuffSize=1kB, MaxMultSect=1, MultSect=off
 DblWordIO=no, maxPIO=0(slow), DMA=no
 CurCHS=123/2/32, CurSects=7872, LBA=yes, LBAsects=7872
I have kept the Personaware software and utilities for reference purposes, since they provide the only mechanism for controlling some of the hardware features (like the BIOS power save modes).

A standard RedHat 4.1 Linux install recognised the PCMCIA disk as /dev/hdc and happily used it without needing the PCMCIA drivers. The output of /sbin/hdparm -i /dev/hdc is:


 Model=Integral Peripherals 8340PA, FwRev=YVJW6900, SerialNo=JS102052
 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
 RawCHS=771/16/54, TrkSize=0, SectSize=0, ECCbytes=4
 BuffType=3(DualPortCache), BuffSize=32kB, MaxMultSect=16, MultSect=off
 DblWordIO=no, maxPIO=0(slow), DMA=no
 CurCHS=771/16/54, CurSects=666144, LBA=no
I haven't tried tinkering with any of these settings yet, except to set the spin-down time with /sbin/hdparm -i /dev/hdc.
