Hello!
I've just tested Linux 2.6.19 on Toshiba Portege 300CT. It's a
"half-PCI" laptop, in the sense that it has a PCI but not all essential
devices are shown by lspci. In particular, the IDE controller is not
seen in the lspci output:
00:00.0 Host bridge: Toshiba America Info Systems CPU to PCI bridge (rev 26)
00:02.0 CardBus bridge: Toshiba America Info Systems ToPIC95 (rev 07)
00:02.1 CardBus bridge: Toshiba America Info Systems ToPIC95 (rev 07)
00:04.0 VGA compatible controller: Chips and Technologies F65554 (rev c2)
00:0b.0 USB Controller: NEC Corporation USB (rev 01)
First of all, I'll appreciate if the description of CONFIG_ATA_GENERIC
is changed to specify that it's a driver for PCI devices only. What I
needed was CONFIG_PATA_LEGACY, but I didn't notice it initially because
it was experimental.
The laptop has a hard drive and a CD-ROM. Neither is detected even with
CONFIG_PATA_LEGACY. The problem with IDENTIFY reminds me problems I
reported earlier with an IBM laptop. The difference is that it's the
present devices that fail to be detected, not the absent ones. As a
result, the system only boots to initrams.
Unfortunately, the Toshiba laptop is way too slow and disk-challenged
for me to try the libata git repository on it. But I think I'll post
the results from 2.6.19 anyway in case anyone cares.
This was captured on the serial console.
