And how do you know that SATA 0 is 0 and not, say, 3? :-)
Ummm.. well.. Based on the SATA0 label on the motherboard, and the fact that the drive is the first one detected by the BIOS... so based on that.. I am calling it SATA0 :-)
Ah, yes. Makes sense :-) Mine are not labeled, or I can't see the labels. I figured them out by unpluging one by one. Then, I wrote labels on the metal sheet nearby and the cables.
/dev/sda = SATA2 /dev/sdb = SATA3 /dev/sdc = SATA4 /dev/hdc = SATA0 /dev/hdd = SATA1
Note that this time the two 1TB drives are picked up as hdc and hdd instead of sdd and sde.
huh? :-o
Exactly. But.. the replies on this thread got me to poke the BIOS a bit more, and I think maybe I've uncovered part of the reason for this... maybe. I have three advanced options for my onboard SATA controler(s).... One to enable it... One to set the SATA type (Native IDE, RAID, or AHCI) and the third... which might be the root of the weird drive order and detection... it's called "OnChip SATA Port4/5 Type" and I can choose between As SATA Type and IDE. The help for the IDE setting says that the SATA Port 4/5 Work at IDE mode. So.. guessing here... what I've been calling SATA0 and SATA1 are on Port4/5... and it was set to IDE mode... so in the case of Gentoo, it picked up the drives as IDE... thus hdc and hdd. The reason.. and I'm guessing here.. that it's hdc and hdd is because that controller looks to be sharing with the PATA controller in some way and the unused IDE0 and IDE1 would be picked up as hda and hdb? As I said.... just guessing while I try to figure this all out.
I think it is similar to what I have. I made photos or the bios screens (American megatrends), to aid me. It says it has an "on board e-sata controller", set to mode "ide" (the exact text on the bios display says: "Raid mode: ide"). There is an "extra raid/ide controller", also on mode "ide". And there is an "on-chip sata controller", also mode "ide". The modes can be ide, raid or ahci. I think I should use ahci, but if I do, the drives dissapear even from the bios and the board does not boot. If I set all to pci, then the bios lists sata1 to sata6, then ide primary master and slave (not plugged), then sata7 and 8, and finally, e-sata1 and 2. They only work if set to "ide". Go figure. And correspondingly, linux (oS 11.2) does not load sata drivers: lsmod: ide_pci_generic 5484 0 ide_core 148064 1 ide_pci_generic ata_generic 6508 0 pata_jmicron 4552 0 However, I get features like hopluging drives, which I use. Using lspci, I see: 00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port SATA IDE Controller 00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller 04:00.0 SATA controller: JMicron Technology Corp. JMB362/JMB363 AHCI Controller (rev 03) 04:00.1 IDE interface: JMicron Technology Corp. JMB362/JMB363 AHCI Controller (rev 03) 05:00.0 SATA controller: JMicron Technology Corp. JMB362/JMB363 AHCI Controller (rev 03) 05:00.1 IDE interface: JMicron Technology Corp. JMB362/JMB363 AHCI Controller (rev 03)
Otherwise, you have one grub in the MBR, as master grub, and this will load another grub (in any boot partition) as needed, chaining menus - but "makeactive" will not work. The advantage is that you need not use primary partitions and the number of grubs is not limited.
This might be ultimately the way I'll go with it... once I can get it all sorted :-P
Good luck :-) - -- Cheers, Carlos E.
