[linux] Re: DMA nejde zapnut na 120GB+nforce2

[Peter N. Vargo (LTS)]

Vyriesenie AKEHOKOLVEK problemu s nforce2 a linux:

jadro 2.4.21:

zakompilovat priamo do kernelu:

1. AMD Viper chipset

2. i810 zvukovku (ano! vid HELP v menuconfig - resp. google)

(len pokial sa jedna o MCP-T (obsahuje na rozdiel od MCP) aj firewire,
usb2.0, nvnet (nvidia NIC))

3. 3com sietovku



spominany nf2 nemal VGA

potom nie je zaden problem s rychlostou HDD, DMA a hdparm - vsetky
parametreidu menit

hdparm -t je pri 120GB/8MB Hitachi (IBM) cca 53-57MB (namiesto 2.4-2.8MB!)

linky pre tych, kt. z roznych dovodov nexcu 2.4.21 ale nizsie, popr.
2.5.relativne_stare:
