We don't > support that for pccard (or usb) at this time. what the deal is actually about is that the vaio n505x/se/* (celeron/pii boxes, not the pentiums) have atapi boot support for cdrom on a pc card. they probe the pcmcia socket at cold boot and attach the ata controller at ports 0x180 and 0x386 (some black magic, one just has to know). i have linux installed this way on my n505x by telling the kernel at boot time to hook up the pccard ide controller as ide2 appending "ide2=0x180,0x386" to the lilo command line and there you go ;-) the only time you would need that is for booting the install cd, since those boxes only got one pc card slot which basically means: cdrom OR network, there you go... while actually installing the dist from the cd (which implies booting from the cdrom through the bios floppy emulation code and loading the ramdisk image from the eltorito image which gets booted) this just means that the kernel once in his lifetime gets the address of the controller hardwired one time. after install is done and you boot you got pccardd which handles the device attachment. > > Other than that, I think that these devices will work with -current > and -stable. if it dynamically attaches ata this should not be much of an issue, but as i mentioned before, installing is ;-) the problem with the little vaios is, that if you boot it from floppy, everything will be fine until you swap the disks since bios boot support for the floppy drive is just for booting. when the kernel wants to read the ramdisk image it gets confronted with a rather unlikely-to-be-supported-natively usb floppy (y-e data flashbuster 3.5"). if the kernel would use the realmode bios irq interface to the floppy to load the ramdisk image it might work to get all that stuff into the mfs and fetch the dist over the network card using a standard ftp install. /k -- > "Dope will get you through times of no money better that money will get > you through times of no dope." -- Gilbert Shelton http://www.webmonster.de http://www.apache.de http://www.splatterworld.de (NIC-HDL KR433/KR11-RIPE) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
