- the hard drive controller is an UDMA-capable controller, at speeds up to 100 MB/sec burst rate at least.
- the chipset in the controller is known as the ICH3M (82801CAM), and as far as I can tell...and I am NOT sure...this chipset had problems being supported properly in kernel 2.4.19. Please correct me if I am wrong!
- the kernels 2.4.18 and 2.4.20 have apparently fixed this problem...? Not sure.
- the hard drive is an IBM Travelstar 40GN 20GB ATA/100 2.5in 4200RPM Mobile Hard Drive, so it too is capable of higher speeds
At any rate, I prepared a floppy installation disk with blank.img, and copied the kernel that comes with Redhat 8.0 (2.4.18), and sure enough it worked...after it booted up, I was able to see the Mandrake screen to begin installing (choose language, etc.). The Redhat kernel did NOT identify the IDE chipset correctly however, instead it identified it as a PIIX4 chipset instead of ICH3M. Visiting Intel's web site confirmed that ICH3M is backward compatible with PIIX4, the main difference of course being higher speeds in ICH3M presumably.
So...if anyone has anything further to add...that'd be great. However I'm going to try and install with my cobbled Redhat/Mandrake installation floppy and Mandrake CD's, then deal with the resulting system later (perhaps it won't boot properly because the kernel that Mandrake uses is buggy with ICH3M, but I'm hoping I can boot using the floppy and then build a new 2.4.20 kernel with stable ICH3M support in it...).
Hey, if you think this is all wrong, let me know, k?

Subject: [newbie] Installation freeze after detecting IDE hard drive & CDROM
Date: Sat, 30 Nov 2002 16:20:14 +0300
I'm trying to install Mandrake Linux 9.0 on a Toshiba Tecra 9000, and
I'm running into very early trouble... I've downloaded all three CD's
from Mandrake's mirrors, and successfully used them to install Linux
on a different desktop machine. But I can't seem to figure out the
problem for getting it installed on the Toshiba laptop (Tecra).
Regardless of whether I try CDROM-based installation or floppy based
installation (and I've tried cdrom.img and hd.img on the floppy), they
all fail at exactly the same point, and here is the snippet right
before the system freezes without any further activity (I'm typing it
in from my notes):
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ICH3M: IDE controller on PCI bus 00 dev f9
PCI: Found IRQ 11 for device 00:1f.1
PCI: Sharing IRQ 11 with 00:1d.2
ICH3M: chipset revision 1
ICH3M: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xcfa0-0xcfa7, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xcfa8-0xcfaf, BIOS settings: hdc:DMA, hdd:pio
And then nothing more...
I've tried utilizing different installation "strings" but all to no
avail, one of those strings is as follows:
expert hdc=cdrom ide0=noautotune ide1=noautotune ide2=noautotune ide3=noautotune
I've been struggling with this for almost a day now, so if you have
any suggestions, I'd really appreciate it. I'm trying to convince my
department to use Linux, and this would look really bad if I can't get
this machine running...*sigh*
Hardware specs:
Machine: Toshiba Tecra 9000
Hard Drive: IC25N020ATCS04-0 on primary channel as master
DVD/CD-ROM drive: Toshiba DVD-ROM SD-C2502 on secondary as master
IDE ATA/ATAPI controller: Intel 82801CAM Ultra ATA Storage Controller - 248A
By the way, the laptop already boots up fine under Windows 2000 Professional.
TIA
