PS2 Boot Disk SCSI CDrom Made a boot floopy exactly as you said and double checked it three time to be sure I had it all correct. Well I need it now on the resurected Server 500/390. The boot disk gives the following on the screen ASPI4B ver 3 installed SCSIMGR HIMEM tested ok SCSI CD-ROM Loadable Driver ver 2.42B Error No SCSI CD-ROM drive found A:\>LH a:\MSCDEX ID:IBMCD001 /M:10 Device Driver not found: 'IBMCD001' No Valid CDROM device drivers selected When I set up the raid 1 I could see the CDR in position 7 so I guess it is working okay. The raid described it as IBM CDRM00201. On the actual unit it is a Toshiba XM-4101BME. An OEM for IBM. Have seen nothing like it before. It is mounted vertically with an odd spindle which must grip the CD as there are no lugs on the outer rim to hold the cd in place. Cannot locate drivers on the web but found people looking for the driver in forums, but no answers. Do you think from the above error message it is not covered by your disk ? Lord Basil, there is a RAID CDrom driver on the Cheetah option disk. The standard IBMCDROM.SYS does not work. I am reinstalling Firefox now, after I updated the MS installer...

If DOS is not already installed, first install DOS in the boot drive connected to Streaming-RAID Adapter/A. 2. Insert Streaming-RAID Adapter/A option diskette into diskette drive and type CD DOS and press Enter. 3. Type UINSTALL and follow instructions to complete installation of necessary driver and support programs for CD-ROM support. First option disk. DOS directory. This installation option installs the RAID DOS Support Software in the directory and drive that you select. The CONFIG.SYS file on the root directory of the selected drive is updated with DEVICE=IBMRAID.SYS, DEVICE= RDASPII.SYS, and DEVICE=RDCDROM.SYS. If a CONFIG.SYS file is currently present in that directory, it is saved prior to the modifications as CONFIG.Snn where nn is two numeric characters, ranging from 00 to 04. The AUTOEXEC.BAT file is updated to install the Microsoft CD-ROM File Extensions Software, MSCDEX.EXE. The AUTOEXEC.BAT file, if present already, is saved prior to the modifications as AUTOEXEC.Bnn where nn is two numeric characters, ranging from 00 to 04. Make sure your config.sys and autoexec.bat both have the same IBMCD001 or else the driver install bombs.

On the actual unit it is a Toshiba > XM-4101BME. An OEM for IBM. Not all CD-ROM drives work with that driver setup, mine Toshiba did not too. I boot with the OS/2 Warp 3 install diskettes to use the CD-ROM to copy files to the disk. What are you planning to ultimately run on this machine? On my PC Server 500, Windows NT 4.0 and OS/2 Warp 3 (Warp Server 4) both installed easily from CD-ROM using their own respective boot diskettes. Their was also something about having to set the SCSI ID jumper on the CD-ROM drive to ID 5 (IIRC), if it is connected to the RAID backplane pass-thru connector. Something about the backplane adding 1 to the device ID, making the CD-ROM, effectively, ID 6.
