@Brendan: While we're on the subject, I have mentioned in the article that if you are no-emulation El-Torito booting, the int 0x13 extensions will almost certainly be there. Am I correct in thinking that, or should I remove this statement?
I think that's a safe assumption - The Enhanced Disk Drive Specification (Phoenix) was first released in January 1994 while El Torito was first released in January 1995; and El Torito does say:
El Torito Version 1.0 wrote:
4.2 INT 13 Function 48
The IBM/Microsoft INT 13 extensions use function 48 for returning drive capability information. The Phoenix Enhanced Disk Drive Specification adds to this information by providing a pointer to a table which contains extended drive information. Byte 10, bit 6 of this table is set to 1 if the attached device is a CD-ROM. This function gives software residing on a CD the ability to determine that it is running from a CD-ROM.
Cheers,
Brendan
