I picked up the ``latest'' ppa.tar.gz which unpacks into ppa_1.42 but could
also be ppa_1.41 according to dmesg...

Start off with booting linux (RHL 5.0/Intel). Try ./ppa_1_42/common/id_probe

Probing port 03bc
Probing port 0278
Probing port 0378
    SPP port present
    ECP with a 16 byte FIFO present
    Passed Intel bug check.

Fine. Then insmod ppa_1_42/ppa_mono/ppa.o and run dmesg

ppa: Version 1.41
ppa: Probing port 03bc
NatSemi PC87332 (or variant) at 0x0378
Old reg1 = 04
Old reg2 = 88
ppa: Probing port 0378
ppa: SPP port present
ppa: EPP 1.9 with software direction protocol
ppa: Found device at ID 6, Attempting to use EPP 32 bit
ppa: Communication established with ID 6 using EPP 32 bit
ppa: Probing port 0278
scsi1 : Iomega parport ZIP drive
scsi : 2 hosts.
  Vendor: IOMEGA Model: ZIP 100 Rev: C.19
  Type: Direct-Access ANSI SCSI revision: 02
Detected scsi removable disk sda at scsi1, channel 0, id 6, lun 0
SCSI device sda: hdwr sector= 512 bytes. Sectors= 196608 [96 MB] [0.1 GB]
sda: Write Protect is off
 sda: sda4

So, run ./ppa_1_42/common/id_probe again

Probing port 03bc
Probing port 0278
Probing port 0378
    SPP port present
    EPP 1.9 with software direction protocol

What happened? Any hints are greatly appreciated.

TIA,
