10.5.1. Q: Can Mondo handle CD-RW?

A: Yes. Use '-Ow <speed> <device>' to make it work.

10.5.2. Q: Does Mondo support tape drives?

A: Yes. See above.

10.5.3. Q: Does Mondo support my tape drive?

A: If your tape drive and its firmware and the kernel-level driver support fopen(), fread(), fwrite() and fclose() - standard C library calls - then yes, Mondo should support it. If not, well, you need a refund. :) Mondo plays nicely with any sane, sensible drives. That's most of them, by the way. :) If your drive doesn't play nicely with Mondo then you may try tinkering with setblksize and defblksize using 'mt', or tweaking Mondo's block size by recompiling it with make INTTAPE=4096 or INTTAPE=8192 or something. Other than that, you need a priest or a refund.

10.5.4. Q: How do I copy the floppy images from the CD to floppy disks?

A: Mount the CD-ROM, e.g. at /mnt/cdrom. Insert a blank floppy. Type:

bash# cd /mnt/cdrom/images
bash# dd if=mindi-boot.1722.img of=/dev/fd0u1722

Insert another blank floppy and type:

bash# dd if=mindi-data-1.img of=/dev/fd0u1722

Do the above for each 'mindi-data' disk image.

10.5.5. Q: Sometimes, my laptop won't mount Mondo CD properly, or something. Umm...

A: Please insert the CD, close the CD-ROM tray, wait a few seconds and then press Enter to acknowledge insertion of the next CD. Your laptop is on crack and is sucking a little too hard on the pipe.

10.5.6. Q: Does Mondo support Hardware RAID?

A: Yes. You may backup and restore RAID systems. You may also backup a non-RAID system and restore as RAID (or vice versa) by using the mountlist editor to edit your RAID and non-RAID partitions and their settings. Mondo will do the partitioning and formatting for you.

Tested Raid controllers includes all those showind only classical devices such as /dev/sdx, and SmartArray cciss controllers.

10.5.7. Q: Where is my CD burner, in SCSI terms?

A: Type:

bash# cdrecord -scanbus

Find your CD burner's device# (e.g. '0,0,0'). Call Mondo with the switch '-Oc <speed>' -d '<device>'. Or, if you feel lucky, just use '-Oc 2'; Mondo will (a) assume you want to write at 4x to a CD-R and (b) will do its best to find your CD burner.

10.5.8. Q: Can Mondo handle SCSI devices?

A: Mondo should be able to handle almost any hardware. So long as your kernel and modules support it, Mindi will support it and therefore so will Mondo.

10.5.9. Q: Why doesn't cdrecord -scanbus work ?

A: If you have a 2.4.x kernel (typical example are fedora legacy kernels for redhat 7.X/8/9) and an IDE CDRW device, and the drive is not listed when you run

bash# cdrecord -scanbus

try adding the following kernel option to your boot script to enable SCSI emulation: hdx=ide-scsi, where "hdx" should be replaced with the appropriate drive letter of the CDRW device, e.g., "hdc". (Answer provided by Christopher Moriarity cdm7_at_cdc.gov)
