the 4GB SSD drive is reported as hdc
the 16GB SSD drive is reported as hdd
the lspci above stated ide controller so it a SATA SSD drive.
I've scoured the bios settings, but I cannot change it emulation between scsi (sata) or ide?
any comments or thoughts are appreciated! |

nimar,
You want kernel setup
All your drives will have /dev/sd* names so yu may need to fix /etc/fstab and grub.conf

nimar,
yes. Very new kernels have an extra submenu in the libata kernel branch where you select the SATA drivers
you will need that on.
Also, I believe your wireless driver was added to the 2.6.27 kernel.

I'm on 2.6.26 r3 so I've been using madwifi HAL and it works like a charm.

Ha! i forgot boot (grub)commands since I copied the "new" kernel over I can't boot. it's fitting.
can I boot using grub commands like root=sd0 or the like??
Many thanks

Since it's now "working" as it should I'd like to optimize the settings. should I use hdparm or sdparm?
Thx

nimar,
There is very little to optimise. SCSI requires that DMA be used, so it is.
You can play with accoustic settings and power down time but neither of them make much sense on a SSD.
You can safely try both hdparm and sdparm.
