I grab the today build but like the yesterday, it doesn't detect my scsi
card. I open a shell, type modprobe sd_mod, retry detect hardware and it
complains about missing modules like ncr symbios logix, ide and usb stuff
:/ I use the

Here is a cat /proc/pci extract:

Bus  0, device  16, function  0:
    SCSI storage controller: LSI Logic / Symbios Logic 53c825 (rev 19).
      IRQ 23.
      Master Capable.  Latency=32.  Min Gnt=17.Max Lat=64.
      I/O at 0x1400 [0x14ff].
      Non-prefetchable 32 bit memory at 0xfeeae000 [0xfeeae0ff].
      Non-prefetchable 32 bit memory at 0xfeeaf000 [0xfeeaffff].

When the missing modules will be available ?
