First an apology, dma_timer_recovery should be dma_timer_expiry. There was no change upon disabling ACPI. Is there a way I can dump the screen output to floppy as unattended boots, so I can send you a copy? A lot of it flashes by too quick to read. :) > > The 4.3 dos cd is readable, but not bootable.

All systems. > What message, if any, do you get when you try to boot it? On an IBM PC300, there is a short pause while the CD is accessed, then it displays "Boot from ATAPI CD-ROM : No bootable CDROM found". Some have Diamond Data 48X drives and some have Samsung SC-152 drives. On an Optima, "Boot from CD :" appears, there is a long pause while the CD is accessed (maybe twenty seconds), then it gives up and tries to boot from the hard drive without displaying any further information about the CD. As the Optimas aren't quite homogenous (some have different Intel motherboards, despite otherwise identical hardware), I tried a couple of them, same result. The one with a different model CDROM (Diamond Data 52x) was different; it didn't even recognise the disc as valid (rapidly blinked the access light and skipped straight to booting off the hard drive). > We upgraded ISOLINUX to version 2.10-pre7.

I'm not using PXE as most of the Optimas have an Intel boot agent firmware version (non-flashable, sigh) that doesn't want to cooperate, and the IBM PC300s have some unknown agent that simply ignores it (assuming their BIOS setting actually does anything at all when enabled :p). > Thanks for the feedback! Most welcome! School break is over so I should be more responsive to queries now.
