Hello!
I'm having some problems using the following setup:
SCSI emulation on my CD-rom's (SCSI emulation, SCSI support, SCSI cdrom support and SCSI generic driver) The CD-rom's are (on ide1): PLEXTOR CD-R PX-W1610A (master) CREATIVE DVD-ROM DVD6240E (slave) I also have two hdd's (on ide0): IBM DeskStar 60GXP 40GB (master) Seagate ST315320A (slave)
My motherboard is the Asus A7M266 (with the Via VT82C686B south-bridge)
The kernel is 2.4.2
Now, if I don't include via chipset support, my hdd's run at ATA100 (IBM) and ATA66 (Seagate). If i include the via chipset, they both run at ATA33, which I can't change.
When not using the via chipset support, my Plextor drive won't mount cd's (the creative cd-rom works fine in both modes) though it still burns fine.
/var/log/messages include: ide-scsi: The scsi wants to send us more data than expected - discarding data 68 times
and right after: can't determine CD-Format.
when i try to mount
If I include the via chipset support, the cd mounts with Plextor, but the hdd's (as already stated) runs slower (about 10MB/s)
Also, the information in /proc/ide/via: ----------VIA BusMastering IDE Configuration---------------- Driver Version: 3.20 South Bridge: VIA vt82c686b Revision: ISA 0x40 IDE 0x6 BM-DMA base: 0xd800 PCI clock: 33MHz Master Read Cycle IRDY: 0ws Master Write Cycle IRDY: 0ws BM IDE Status Register Read Retry: yes Max DRDY Pulse Width: No limit -----------------------Primary IDE-------Secondary IDE------ Read DMA FIFO flush: yes yes End Sector FIFO flush: no no Prefetch Buffer: yes no Post Write Buffer: yes no Enabled: yes yes Simplex only: no no Cable Type: 40w 40w -------------------drive0----drive1----drive2----drive3----- Transfer Mode: UDMA UDMA UDMA UDMA Address Setup: 30ns 30ns 30ns 30ns Cmd Active: 90ns 90ns 90ns 90ns Cmd Recovery: 30ns 30ns 30ns 30ns Data Active: 90ns 90ns 90ns 90ns Data Recovery: 30ns 30ns 30ns 30ns Cycle Time: 60ns 60ns 90ns 90ns Transfer Rate: 33.3MB/s 33.3MB/s 22.2MB/s 22.2MB/s
Dosen't fit with the cables I use - they are both 80 pins (and the BIOS acknowledges this)
hdparm -i /dev/hd[ab] (when using the via chipset support): /dev/hda:

I tried using the via kernel parameter to hardcode the UDMA transfer-rates but nothing happend.
