I misread your message. You're trying to get the Promise IDE working at 100, no? My Asus A7V133 has the 686b which does ATA100 without having to rely on the Promise chipset, and that seems to work fine. But if it helps to know, I've got an A7V with the 686a and I use the PDC20265 for my ATA100 drive. It boots with a message that says it's doing UDMA(100): hde: 80041248 sectors (40981 MB) w/2048KiB Cache, CHS=79406/16/63, UDMA(100) But /proc/ide/pdc202xx says: PDC20265 Chipset. --------------- drive0 --------- DMA Mode: UDMA 4 Shouldn't that be UDMA 5? -Nick I have the same motherboard, and it works fine for me. Note the 80w cable detection. Perhaps you've got a bad cable? -Nick ----------VIA BusMastering IDE Configuration---------------- Driver Version: 3.23 South Bridge: VIA vt82c686b Revision: ISA 0x40 IDE 0x6 Highest DMA rate: UDMA100 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: 80w 80w -------------------drive0----drive1----drive2----drive3----- Transfer Mode: UDMA UDMA UDMA PIO Address Setup: 30ns 30ns 30ns 120ns Cmd Active: 90ns 90ns 90ns 90ns Cmd Recovery: 30ns 30ns 30ns 30ns Data Active: 90ns 90ns 90ns 330ns Data Recovery: 30ns 30ns 30ns 270ns Cycle Time: 20ns 20ns 60ns 600ns Transfer Rate: 100.0MB/s 100.0MB/s 33.3MB/s 3.3MB/s
