The box now has a blank 9.1Gig 68pin SCSI disk and it's recognized.

I have 5.1 on CD, this starts to boot from the internal 68pin IBM CD-ROM then hangs with LED 518.

A bit of searching says "need to update CD-ROM firmware".

I update the machine's firmware (TIG04204) and still get the same hang.

So how do I update a CD-ROM's firmware, and with what from where?

So I now look for another SCSI CD-ROM and notice the external SCSI connector, damn, too many pins. But it has an internal unsupported 50pin connector, so I am now installing AIX from a 50pin CD-ROM hanging from a 50way umbillical cord off the unsupported internal 50pin connector....

But the question remains, how do I update the CDROM's firmware?

I've got an RS6000 external SCSI cable I'd part with - PM me if you're interested.

Is that the original CD-ROM which comes with the machine? Sounds quite strange, as IBM does not offer a firmware for CD-ROMs in the 43P-140.
Have a look at this page, there are a few microcodes for CD-ROMs:

On a related note, I got me a ultrawide scsi CDROM (Plextor 40x) which has IBM firmware on it. Works great, I installed Solaris 10 sparc off of it. Only issue is the eject/inject button up front wont work. eject/inject commands work fine under irix (eject command works fine under solaris). I tried to flash the drive with Plextor firmware I downloaded from plextor's site, buuuuut...the drive was not even recognized by the flashing app (plugged the drive to a windows box to do this). I was not suprised, as IBM firmwared seagates also refuse to take seagate (or Sun) firmware updates.

Drive has less jumpers than the non-oemed Plextor (there's pads on the pcb where those extra jumpers should have been). There *is* one jumper that controls the eject mechanism, but the drive behaves just the same with the jumper open or closed.
I believe this drive's current firmware is meant to disadble the button (several server cdroms have that feature) in order to prevent media inside from being mistakenly ejected.

Drive is a Plextor PX-40TSi, dated april 2003, IBM FRU 97H7796 (P/N 04N2964).
Anyone had a similar issue (and a possible solution)??


There's a firmware update on the page listed above, but apparently it will only work from within AIX . And my drive probably has that firmware based on the mfg date on it.

Many thanks, that was indeed the place. Turns out it is a 32x CDROM



I was able to boot AIX 5.1 from an external CDROM connected to the internal 50pin connector, do the patch of the microcode, and have since tested booting from the installation CD-ROM using the internal drive.

Nice to hear, many thanks for your feedback!
