Okay, I dusted off one of my old (actually, I believe *the oldest*)
Zip100 drives in the collection, and tried it out here with both
2.6.20 and 2.6.21-rc3-git9. It works mostly fine with each.
A couple of minor issues, though.
(1) When ejecting a disk, either with the "eject /dev/sdc" command
or using the front-panel soft-eject button on the drive,
I get the following in syslog from libata:
sdc: Spinning up disk...<3>ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2
res 00/00:03:00:00:20/00:00:00:00:00/a0 Emask 0x2 (HSM violation)
ata4: soft resetting port
ATA: abnormal status 0x7F on port 0x00010177
ATA: abnormal status 0x7F on port 0x00010177
ata4.00: configured for PIO2
ata4: EH complete
(2) The above log says PIO2, but the IDENTIFY data for this drive,
which I had to patch the kernel to get (ATAPI ATA_16 support),
indicates max PIO0 for this unit. I suppose maybe the chipset
doesn't go that low, but no big deal since IORDY handshakes it anyway.
Chipset is VIA, PCI ID 1106:0571, Rev.6.
Tejun, if you want one for your testbed, then email me shipping
info (again) and I'll send you this exact unit, with one disc.
Here's the IDENTIFY data, for anyone else here who collects antiques:
