Morris @ 2002-05-17 13:26 UTC (permalink / raw) To: LKML This is probably approaching blasphemy, but has anyone ever considered an emergency EIDE driver that uses the extended int13h calls? I'm pretty sure there's a protected-mode BIOS interface in modern BIOSes these days, so it shouldn't need to go down to real mode to make the calls. I have just purchased an IDE RAID controller to add tertiary and quaternary IDE ports to my system for an extra CDROM drive. I thought the days when you couldn't get Linux support for such things were long gone, but sadly no. The culprit is an ARALION ARS106S chipset card. Interestingly it works in DOS, and if the hard disks are attached to it, it will even boot up to LILO, but then the kernel dies because it can't find the HDDs. (On their web page message board, some guy asks for the specs but is helpfully pointed to an obsolete binary module for RedHat 7.1.) If there was Linux support for BIOS-based EIDE controllers, it should in theory work, if slowly. Alternatively, can anyone suggest a cheap tertiary EIDE card suitable for CDROM or hard disks that Linux can support? -- JP Morris - aka DOUG the Eagle (Dragon) -=UDIC=- jpm@it-he.org Fun things to do with the Ultima games http://www.it-he.org Developing a U6/U7 clone http://ire.it-he.org d+++ e+ N+ T++ Om U1234!56!7'!S'!8!9!KA u++ uC+++ uF+++ uG---- uLB---- uA--- nC+ nR---- nH+++ nP++ nI nPT nS nT wM- wC- y a(YEAR - 1976) ^ permalink raw reply [flat|nested] 7+ messages in thread

Later examination revealed it to be some kind of self-extracting ZIP file. Inside are some binary kernel modules they wrote which are specific to RedHat 7.1's version 2.4.2 kernel. They've just updated their Windows drivers, so they -may- release a more recent version, but I'd prefer not to have a closed binary module present. -- JP Morris - aka DOUG the Eagle (Dragon) -=UDIC=- jpm@it-he.org Fun things to do with the Ultima games http://www.it-he.org Developing a U6/U7 clone http://ire.it-he.org d+++ e+ N+ T++ Om U1234!56!7'!S'!8!9!KA u++ uC+++ uF+++ uG---- uLB---- uA--- nC+ nR---- nH+++ nP++ nI nPT nS nT wM- wC- y a(YEAR - 1976) ^ permalink raw reply [flat|nested] 7+ messages in thread

Just install Linux from a current distribution, i.e., like RedHat (not an Add, just came-to mind because I don't know how to spell Suse and/or whatever..). The drivers for IDE/EIDE/RAID are in their installation kernels. If you are trying to build a kernel to support EIDE, the problem is figuring out what questions to answer during configuration. The major distributors have already figured that out. You can't do 'BIOS-based' stuff in the kernel (although it's been tried for what should be simple stuff like APM). The BIOS code itself often makes assumptions about the environment like it can plug its interrupt vector into the interrupt table and enable its ISR. There can't be, as you say, "a protected mode BIOS interface" for the same reason nobody does general purpose surgery. Every protected-mode system is different. Also, when LILO boots, if it didn't get past Uncompressing, then booting the kernel, it's NOT a lack of hard-disk support. You probably have built the kernel for a processor you don't have.
