IBM Thinkpad 755CE - Hard dirve larger than 500MB...
By Phoebe - usenet poster
Have a Thinkpad 755CE and have recently been given a 1.44GB HDD for it,
however I recall hearing about having too cross 2 pins on the connector in
order to ge the drive to work - does anyone know anything about this or a
website (I've tried searching). I believe I heard about it in this or a
similar newsgroup. The problem is the Laptop doesn't boot with a disk that
big in it, it should be possible though. Thanks for any assistance.
If you help me I might be able to help you!

You are quite right! Actually I have got the same problems with a
755CDV. The clue is the master/slave selector on pin 47-50. For older
drives the outermost pins have to be jumpered to be master drive, this
is actually be done with the connector on your caddy. Newer drives,
however, should have both pins open, so this prohibits use of the old
cable/caddy.
I would recommend to cut down the _proper_ 2 pins on the ribbon cable,
or if you are suspicious about it, you can _cautiously_ bend both pins
on the drive connector before you fasten the ribbon cable.
Good luck

Hi Ben,
Got it working - its fantastic - so much faster than my old drive! Thanks.
No luck with the MWave modem as yet - and I haven't a clue on the pin outs
either although I have a 56K PC Card so I haven't really tried. I think I
heard that it disables your sound when you use it at any speed above 28.8K.
And it eats CPU time - so I wouldn't bother personally. 56K modem PC cards
are fairly cheap at the moment and they work in all O/S's so I'd go for one
of those.
As for the DOCK II yes I have had a range of SCSI and IDE devices working:
380MB SCSI-1 HDD
SCSI-2 NEC 4X CDROM
2GB Seagate Barracuda (7,200RPM) SCSI-2 (Have booted from this)
IDE:
200 - 500MB HDD's
32x CDROM (LG)
ISA Cards:
3COM 3c509 10MB Ethernet
PCMCIA:
Samsung 24x CDROM
56K Modem
NDC Instant Link Ethernet (10MB)
10/100 Netgear Ethernet Card
O/S:
Windows 3.11
Windows 95A, 95B, 95C (Currently using Version C)
Windows 98 (Too slow really)
Windows NT 4 (Again a bit too slow)
Slackware Linux (Too difficult to configure)
Redhat 5.2 (Very good very easy to install, very fast)
And Soon SuSE Linux 6.1, and possibly Win 2K although I think that will be
way too slow.
Look on the www.pc.ibm.com site (support and then accessories section I
believe) for the spec sheet(s) - it tells you how to enable the SCSI - BIOS
(there are 4 dip switches inside the docking station). It works under
Linux too which is good. Its an Adaptec ISA card and its auto detected by
windows 9x.
I am about to convert the old 500MB drive into a SUSE linux drive - if you
want any help with Linux (Esp. the setting up the screen under x-windows)
give me a shout. I have had Redhat running on an old 300MB for a while and
that works well.
I'll post that reply to comp.sys.laptops and this one.
Thanks for your help
If ever you need any help with TP / Linux / whatever give me a shout
