pcm-5823 pirq table and ide

[Andrew Ip]

5823 can now get the pirq table with COMPRESS off, but the address of pirq
table which detect from Linux kernel, is different from where LinuxBIOS wrote.
For example, LinuxBIOS writes pirq table at 0xf0000, but Linux kernel found the 
table at 0xc00fd9b0.  However, Winfast 6300 doesn't have this.

Does anyone know how to turn on the second IDE channel on 5823-E0A1?  Enabling
bit 3 and 4 on 0x5b doesn't do the trick this time.  Thanks.
