You forgot to remove the `grub_disk_firmware_is_tainted' hack. That prevents biosdisk from working afterwards (but it doesn't affect my test, see below). > Please tell me (read this before testing!): > > 1) Does it work perfectly (yes/no) as in, all devices are detected and > can be accessed. If no: what's the problem. Hangs during init.

(yes/no) It detected my CD drive (ata3), but was unable to access it. The following command: ls (ata3)/ just hangs, producing no debugging output, and makes ctrl-alt-del stop working as well. It _did_ archieve to make the drive spin, though. > 3) "rmmod ata", "insmod biosdisk" can you still access your disks N/A > 4) Same as 3, but before applying this patch Note: insmodding biosdisk is likely impossible when you can't access the disks ;-) When disabling `grub_disk_firmware_is_tainted', and loading both (preloaded in core.img), I can still access the hard disk via (hd0) (however, note the hard disk wasn't detected by ata.mod, only the CD). > 5) If there are problems, use: > set debug=ata > insmod ata In case this helps: grub> lspci 00:00.0 005e:10de.0 Memory Controller 00:01.0 0050:10de.0 ISA Bridge 00:01.1 0052:10de.1 Serial Bus Controller 00:02.0 005a:10de.0 Serial Bus Controller 00:02.1 005b:10de.1 Serial Bus Controller 00:04.0 0059:10de.0 Multimedia Audio Device 00:06.0 0053:10de.0 IDE Controller 00:07.0 0054:10de.0 IDE Controller 00:08.0 0055:10de.0 IDE Controller 00:09.0 005c:10de.0 PCI-PCI Bridge 00:0a.0 0057:10de.0 Unknown Bridge 00:0b.0 005d:10de.0 PCI-PCI Bridge 00:0c.0 005d:10de.0 PCI-PCI Bridge 00:0d.0 005d:10de.0 PCI-PCI Bridge 00:0e.0 005d:10de.0 PCI-PCI Bridge 00:18.0 1100:1022.0 Host Bridge 00:18.1 1101:1022.1 Host Bridge 00:18.2 1102:1022.2 Host Bridge 00:00.0 94c3:1002.0 VGA Controller 00:00.1 aa10:1002.1 Multimedia device 00:07.0 0002:1102.0 Multimedia Audio Device 00:07.1 7002:1102.1 Unknown Input Device $ sudo lspci 00:00.0 Memory controller: nVidia Corporation CK804 Memory Controller (rev a3) 00:01.0 ISA bridge: nVidia Corporation CK804 ISA Bridge (rev a3) 00:01.1 SMBus: nVidia Corporation CK804 SMBus (rev a2) 00:02.0 USB Controller: nVidia Corporation CK804 USB Controller (rev a2) 00:02.1 USB Controller: nVidia Corporation CK804 USB Controller (rev a3) 00:04.0 Multimedia audio controller: nVidia Corporation CK804 AC'97 Audio Controller (rev a2) 00:06.0 IDE interface: nVidia Corporation CK804 IDE (rev f2) 00:07.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev f3) 00:08.0 IDE interface: nVidia Corporation CK804 Serial ATA Controller (rev f3) 00:09.0 PCI bridge: nVidia Corporation CK804 PCI Bridge (rev a2) 00:0a.0 Bridge: nVidia Corporation CK804 Ethernet Controller (rev a3) 00:0b.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0c.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0d.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:0e.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 94c3 01:00.1 Audio device: ATI Technologies Inc Unknown device aa10 05:07.0 Multimedia audio controller: Creative Labs SB Live!
