Thanks for the advice!
Well, that's what I did. You're right, it built up just fine.
It appears to me that of four identical Maxtor 27GB drives, two will do 66 and
two will only do 33:
Uniform Multi-Platform E-IDE driver Revision: 6.20
PIIX4: IDE controller on PCI bus 00 dev 39
PIIX4: not 100% native mode: will probe irqs later
ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
PDC20262: IDE controller on PCI bus 00 dev 40
PDC20262: not 100% native mode: will probe irqs later
PDC20262: ROM enabled at 0xe7000000
PDC20262: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode.
ide2: BM-DMA at 0xc400-0xc407, BIOS settings: hde:DMA, hdf:pio
ide3: BM-DMA at 0xc408-0xc40f, BIOS settings: hdg:DMA, hdh:DMA
PDC20262: IDE controller on PCI bus 00 dev 48
PDC20262: not 100% native mode: will probe irqs later
PDC20262: ROM enabled at 0xe8000000
PDC20262: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode.
ide4: BM-DMA at 0xd800-0xd807, BIOS settings: hdi:pio, hdj:pio
ide5: BM-DMA at 0xd808-0xd80f, BIOS settings: hdk:DMA, hdl:pio
hda: Maxtor 90845D4, ATA DISK drive
hdc: Maxtor 93652U8, ATA DISK drive
hde: Maxtor 92720U8, ATA DISK drive
hdg: Maxtor 92720U8, ATA DISK drive
hdi: Maxtor 92720U8, ATA DISK drive
hdk: Maxtor 92720U8, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
ide2 at 0xb400-0xb407,0xb802 on irq 16
ide3 at 0xbc00-0xbc07,0xc002 on irq 16
ide4 at 0xc800-0xc807,0xcc02 on irq 17
ide5 at 0xd000-0xd007,0xd402 on irq 17
hda: Maxtor 90845D4, 8063MB w/512kB Cache, CHS=1027/255/63, UDMA(33)
hdc: Maxtor 93652U8, 34837MB w/2048kB Cache, CHS=70780/16/63, UDMA(33)
hde: Maxtor 92720U8, 25965MB w/2048kB Cache, CHS=52755/16/63, UDMA(33)
hdg: Maxtor 92720U8, 25965MB w/2048kB Cache, CHS=52755/16/63, UDMA(33)
hdi: Maxtor 92720U8, 25965MB w/2048kB Cache, CHS=52755/16/63, UDMA(66)
hdk: Maxtor 92720U8, 25965MB w/2048kB Cache, CHS=52755/16/63, UDMA(66)
Even more disappointingly, a raid1 array of hde and hdg shows identical
performance to a raid1 array of hdi and hdk.
After about 30 hours of work on the Promise setup, I can conclude that raid
works fine, but the Ultra66 driver (or my Maxtor disks implementation of
Ata-66) is just not ready for prime-time. It was just never any faster than my
onboard (33MHz) ide.
